Location: Heaven Above (Formerly Oklahoma City,OK) | Steve, I have a set on my '38 (I think they are stainless) but they are caoted with ceramic, so aI can't tell. We do have stainless headers and headpipe on the race car, and they do discolor, but can be polished. Walt |

Location: bishop, ca | Years ago, I bought a set of Sanderson "Block Hugger" headers, for the 315-325 Hemi heads.
Really nicely made; cost $400.00-ish.
Had them for several years before deciding to get around to having them be installed.
My shop confirmed that, altho the passenger's side would fit the OEM application, no-problemo, on the driver's-
side, the front runner contacted the motor mount, and the exhaust-dump aligned very-nicely right over the
torsion bar.
Major bum-out, but Sanderson accepted-back the headers and gave me a full refund (!) of my payment.
What I failed to realize (and my muffler/exhaust shop never volunteered to do) is that SHEEIT; the Sandersons header
flange was already perfectly set-up/aligned to the exhaust ports, so, all that would have to be done is to have "a shop"
re-create/re-route the runners so as to avoid the motor mount and the T/bar !
I realize that long-individual exhaust runners are the most efficient system, but a competent workman could custom
cut standard bends of tubing, and conjoin several runners, as necessary, so as to create a header which would clear the
motor mount, the T/bar, and the starter , in a manner which would be reasonably very efficient (especially compared
to the OEM header).
After the custom-creation of that header, it could be sent out (maybe along with the other-side, to make sure that they both
look alike) for a high-heat treatment.
I've been quoted prices of $1K+ for the creation of custom headers, so the cost of the Sanderson-modification, with heat
coating-treatment, is about the same price.

Location: Heaven Above (Formerly Oklahoma City,OK) | Sandersons' are what I put on the 328 in the 38. Perfect fit, but had to rereoute the steering. Have 1000K+ on them with no discolouration. Only a couple of short runs at 80mph+, so far. Haven't decided whether to put a set on the '55 so far. The block hugger style is what i've used. Walt |

Maybe we could team-up and have several sets done, in a package deal...? I would take one set, and I know others that probably would. |

Location: bishop, ca | The 'trick' is having a shop CUSTOM cut and bend tubing, BASED-upon the Sanderson flange-and-exit-tubing sections, so
that the re-configured tubing, and exhaust-dump/collector avoids conflict with the motor mount, the T/bar, and the
starter.
IF that shop/person would carefully record the pieces/cuts/bends involved in creating a usable header, then additional
headers could be relatively easily created, from that 'template/design' .
Recording and reproducing the multiple-ANGLES of the tubing attachments would probably be the most difficult procedure
in re-creating suitable headers.

Location: Orlando | I had a crazy idea a while back, that I haven't yet tried to implement, but here goes...
I bought some lazer cut header flanges on EBAY a while back for my 325 hemi/ They were only about $45 and look great. Very thick with perfect smooth cuts, etc. I haven't tried to match them up, but let's assume the match the ports correctly. This is the hardest part of building a header out of the way for $45.
THen, I was going to buy some full length headers for for a mustang 5.0. They have close to the correct cylinder spacing and should be the correct diameter/length for peak performance for my 325. I will cut the Ford flanges off and mate it to my hemi flanges. I will also re-route any tubes that interfere with existing engine bay componants.
This will require some creative/custom work, but it get's the MAJORITY of the work out of the way. It's simply modifying existing stuff rather than starting from scratch. And for only $45 plus the cost of some cheapo mustang headers (which can usually be had for less than $100.) If it works, then I might invest in some higher quality headers and repeat the process (it's always easier the second time around, once you've worked out the initial problems.) I'm many months away from attempting this, however. My 325 still needs a rebuild, and that comes before any 'extras.' |

Location: Big pimpin' | I don't know bout the F. Look Chassis cars with the Early Torqueflite and Hemi, but I know there is a real problem getting FULL length headers aon these cars Period......The Tosion bars are just too far over towards the engine to have a "Good" set up....The musclecars torsion bars are spaced futher out towrds the body (outside of car), so full length headers aren't a problem...I HAVE made a set of BB FULL length headers for the '58 Plymouth, BUT! the driver's side leaves ALOT to be desired as far as cooking the firewall/M/C/steering box....I can imagine a Hemi is worse..... |

Location: bishop, ca | Chaney, the Sandersons are shortie-collector types; 4-into-1 type, with the collector located about 1.5' below the level
of the exhaust ports.
Not super efficient, but better (and cooler-looking) than the flat-log that lives 'there', now.
A driver's side manifold is definitely do-able; I contacted the usual (Hedman-) Hedder companies, and they've said that they
no longer have their old dies/records....
Some snow-bound Swede-type could make a killing by figuring out the parameters for a functioning header system!
Tom: the 315/325 Hemi heads have differently configured exhaust ports, from their Poly-cousins.
This project IS do-able, and there IS a market for headers.

Yep, I have a hemi  And these flanges I bought are supposed to be for the hemi. The only problem is that the openings in the flange are 1.75" and for 325ci at 5500, they shouldn't really be more than 1.5" for good gas velocity. I don't know how I'm going to make the transition.
I also considered doing the same thing with some ford 5.0 "shorties", which would be designed to exit from the upper rear of the block, just as the original log manifold. That would almost definitely avoid any routing problems. But as you pointed out, shorties are vastly inferior to full length headers...even if they are vastly superior to the factory log manifolds. Hopefully I can make SOMETHING work, cuz anything is better than the factory units.

Location: bishop, ca | Tom, if you are serious about making these headers, I suggest that you buy a set of the Sanderson Block Huggers, and use
them as templates for the custom-bending/forming of headers which WILL fit our cars.
Sanderson's flange plate is very heavy gauge, and the pipes which exit that flange are already mated-up to it, so that
situation would appear to be the best possible scenario for the creation of the custom-fitted headers.
Heck [sic] , you could just TELL people to go buy the Block Huggers and to send them to you, and that for $X, you will
convert them to fit our cars!
You could, then, offer to re-do the passenger's side manifold, too, for $Y (not really needed, however) and offer to send
out the new manifold(s) for color/heat treating (or, have the customer do that, once he gets the header(s) back, from you).

Location: bishop, ca | If those headers fit a 318 block, then, no, they won't bolt up to a 325 Hemi head. The Hemi exhaust posts are round,
but the 325 Poly heads have square-ish shaped exhaust ports (right?).
NOW, as far as the shape-configuration OF the exhaust runners are concerned....the passenger's side can be almost
purely a straight-down orientation.
Your driver's side configuration might(?) clear the motor mount, the T/bar, and the starter, however.

Location: bishop, ca | Well, they should be a straight bolt-on, since the 326 is merely a bored-out 318.
Thought your '326' might have been a typo---shooda known better!

Location: Netherlands | The Heddman shorty headers work just fine on my '60 NY.
Just a little clearancing was needed at the left motormount.
Because the end up between the torsionbars you'll have to swingaround them again to line up with the crossmember, but nothing an exhaustshop couldn't fix;

I have a 59 Newyorker and I have it set up with air ride so no torsion bars but I need something to clear the steering box can you give me any more detail on these like the exact name or anything so I make sure I get the right ones thank you |
