Heads dont match.

I have a 86-88 350 4 bolt main, Head castings are 093 and 261. The 093 are 64cc heads, cant find no info on 261, I dont know if its a factory replacement head or what. I just need to know if they're the same.

I'm coming up with

14019261 1984-88 350 1.94 1.5

Neither sound like a small chamber head, but I'd get the measuring cup out. If they are 76 cc heads, the 12 cc difference is about 3/4" ^3, should be pretty obvious.

I think that is a 76cc head from an earlier 1980s engine.

093 gives me a bad book. not listed.

a 193 is listed, same years you posted.

76cc was 1970s madness, crap for blocks went with them. Never learned otherwise. Not even good option for turbo.

even then I spotted today was 66 for turbo.

I wonder if the tip in the book could apply, there is a strong head and a weak one..doing same job. looking at certain parts of the head can determine this.

Would they have came on the same engine from the factory?

Would they have came on the same engine from the factory?

seems a good chance. Not a place even the dumbest of mechanics play around. cyl heads are serious.

I am curious to castings.. a guru knows stronger from another, even though the same.
if you really want to get precise, but I don't have any more on the numberings.

[realsteelfreak]

both are listed for 1981-86 ,casting # are a replacement for both

i have a a set of 624's that came on a autobone rebuilder 350 and the two heads have different sized exhaust valve stems :P

[kyhunter89]

Well, I'm still uncertain, I have 74 509 400sbc, that I've had for years. I'm gonna check its condition tomorrow. Would 882, these heads or the original 400 heads work better.

none are real good for big hp, vortechs are cheap
