[Chrysler300] Head castings

["George Riehl" <longrams@xxxxxxxxxxxxx>]

Some time ago, before my computer "fried", I was sent an Email asking about '63 300J and '64 K head (ram and non-ram) casting numbers. Unfortunately, the inquiry was "lost". 
Relying on memory (what's left), I found a penciled note today in a pile of notes which prompted this..........
1963 300J ram head casting..................2402557..73.5 c.c. chamber..4 bolt valve cover
1964 300K ram head casting (early)....2402557..73.5 c.c. chamber.. 4 bolt valve cover
1964 300K ram head casting (late)......2408520..73.5 c.c. chamber..6 bolt valve cover
1964 300K non-ram casting..................2463200..73.5 c.c. chamber..6 bolt valve cover

As a further note...2402557 & 2408520 heads used 2.08 intake valves and 1.74 exhaust valves.
The non-ram 300K, 2408520 casting used 2.08 intakes & 1.60 exhaust valves.
The non-ram 300K used the same hydraulic cam profile as the '60F, '61G & '65L, .430 lift. 

As one point of interest, it is noted that many 1963 part numbers range in the later 2400000 series. 
Since '63 was a bad year for Chrysler, maybe they wanted to get into 1964 a.s.a.p. (?). 

Most all big block heads from '58 were of 73.5 c.cs., up untill '62 Max Wedge of 81 c.c's.
Then the range went from 81c.c's. to 79.5, 81.5, 83.1 to 86c.c's. The difference in c.cs.,were the higher compression pistons (pin location and dome height) that ran from 10:1, 11;1, 11.5:1 to 12.5:1.
