cracked 273 heads

Not so sure what caused the problem, my mechanic thinks in part too large of head gasket & a lean burning valve. I have found a set of heads in Detroit with a 4323302 # on them dose that sound like what i need?? Thanks for your input


OTE=Marcohotrod;1970809940]what caused the problem in the first place? other heads will work, one of the best heads is the 1988-91 318 swirl casting #302 head with around a 60 cc chamber. most other 318 heads are around 64 cc - compression lowering chamber, except the 1967 318 casting #2658920 with a 57 cc chamber. the 1965 intake can be ground or machined around the bolt holes to bolt onto later heads[/QUOTE]
