I was curious if anybody has or knows where I can find flow munbers on a set of ported or unported 292 turbo heads?

I will do some digging but I think my numbers are long since in the trash, lol. They were ported as much as possible without filler, and were under 275 @ 28" if I remember. Plus they have a nasty habit of cracking in the spring seat areas. If you do not have them, I would personally skip them and look at other iron heads.

Just remember that every bench will give different numbers.
