Anybody know where I can find a reference guide to find out how much chamber volume a specific set of heads have? Trying to do a little math.

 

You could try the web site 442.com and go to the FAQ section. That would be a quick and easy resource to check. John

 

Due to production tolerances, the best any "reference" can do is an average. The only way to insure accurate numbers, is to CC them for yourself.

If you would like an approximation, post the casting number.
