casting numbers

[reddishdsb]

does anybody have a list of head casting numbers. i have a 71 440,
just curious about chamber volumes etc. compression ratios.

You should have the 346 casting. Volumes vary from 82cc to 88cc's.Quite the variance...........eh?

will these be ok for mild hot rod?

I don't see why not. I've used them for years, although it might be more cost effective to by a set of Eddy's. Unless the 346's are all refurbished.
