i have a set of 351w stock heads, that are not going on my 393, but was wondering if all 351w heads were the same. just trying to get some specs and wondering if they would fit on the old 302, and if they would i gain anything? not sure what year they are and the only mark on them is 5d19. oh ya they do have smog holes on the back of them. thanks guys

unless they are date coded c9 or d0 then they are the same as 302 heads except for the bolt hole size

ya that would be ****ty if they are, arent they the e5 or whatever. well if they are i will shave the hell out of them, throw them on the 302 and when it ****s i will put in my 393, but thats a couple months awa, that would also give me a reason to get it done faster lol.

e5(1985) pretty much the same as the e7(1987) the c9(1969) d0(1970)

Theyre a little taller too. They're not really worth rebuilding, as the for cost of that, you could get a nice used set of aluminum heads. I considered the same thing, but found a set of Edelbrock's cheaper than the guy quoted me to rebuild the damn 351 heads that are pretty much junk!
