head # ?

i have 2 different head casting numbers on my 350. the #s are 333882 and 3998997. both are supposed to be 76cc heads off of a 350 or 400. is this a big deal. should i try to find a matching head #? if so what head is better?

Re: head # ?

333882.....74-80...350/400......76cc chambers

3998997....78-84...305/350......76cc chambers

This is the best site I have found for looking up casting numbers
