Re: [Chrysler300] 331 Heads

There are several versions of 331 heads so you have to qualify what you want. 
If your talking about a 1955 331 in a 300 and you want #s to match, your 
approach has to be a little different than if your just rebuilding the top 
end. Differences between a 1955 and 1956 are cosmetically minor. Rockers, 
pushrods, etc will swap from a similar application. There are, however, 331 
truck and industrial heads that are much different and Pre - 55 331 heads 
come in two major variations that won't work for a 300. The big valve, oval 
exhaust ports, with water crossovers at the front and rear are what you need. 
Casting #s are on the Power Play website.
