Re: [FWDLK] hemi heads on 325 motor

Fred,

Yes. All Dodge Hemi heads will fit your 325 Poly. The only problem is that
the Poly block has relocated pushrods and a small "bump" opening at the
block/head interface that may leak oil when Hemi heads are used. You can
probably seal it up. Early (241/270) Dodge Hemi heads will have much smaller
valves and ports, probably resulting in a lower total HP than you have now.
Later (315/325) Hemi heads have bigger ports, but are much harder to find,
because they only came on high performance D500 engines and a few 57 - 59
Dodge trucks. Valve notches in the pistons are located differently, but
should not be a problem. Parts you will need:

Hemi heads from a Dodge
Valve covers for Hemi
Rocker arm assembly for Hemi
Head bolts for hemi
Pushrods for Hemi (315 adjustable/325 hydraulic)
Exhaust manifolds for Hemi
Intake manifolds for Hemi/Poly are interchangeable. 4 bbls are hard to find.
You need one from a 315/325.

A longer duration cam will wake up the engine.
