Highest flowing sbm heads?

I'm happy with the old builds and I go slow, real slow. I spend little, very little. But I have big fun, lots of fun. :)
That's funny Dan Smith runs mid 9's with the **** most guys will throw away like stock cast iron heads and a stock factory block with just a flat tappet cam. **** you could probably build 2 for the prices these guys will pay for 1 that will do that. The fact that its done 2600 passes without breaking says EVERYTHING about its reliability. **** he's even doing it with Eddie heads. He's obviously figured out how to make a lot of power with parts people consider junk and that's gonna piss off those that need exotic and expensive parts to do it.

It is what it is. Cue the haters.........
