Which heads?

My post wasn't meant to be insulting or argumentative......BUT, the point I was trying to make is, on the one hand, we have a professional engine builder with several dyno pulls showing what head flow can do on a low compression engine. Yes, it's a big block.

On the other hand, we have several people giving their opinions (and experienced opinions I am sure) of what they believe the case to be. One is based on fact (although again, it's not a small block) and the other based on opinion.

Yes, I agree with Rob......there is NO definitive proof this will work for a small block, BUT, common sense says it probably will. IMO, there's a stronger case for the 308 heads. But again, that's just another opinion, although with some "loose" proof that it might be the right opinion. Maybe Jim (IQ52) has done a 318 before. Maybe he intends to. It would be nice to see how the small block would react. I THINK that the head with the best flow will win out every time. And I BET that the 308 has the best flow.

Of course as Rob has pointed out, all of this, BOTH sides is merely speculation.
