331 Heads

[Hardy Graham Jr <hpgraham@xxxx>]

Are all the Head components interchangable between the 331 and the 354? The
PAW "Early Chrysler Hemi" catalog lists many parts for the 354 but not he
331. Are valves, push rods, rocker arm assemblies, etc. interchangeable? I
have been told that the only significant differance is the bore size.

Thanks,

Hardy
