I know what GTP advertises. Perhaps they would flow that well on another bench, but this one showed EXACTLY 300cfm at .600" lift. The bench they were tested on usually has AFRs around 290cfm. Regardless, the heads made good power and definitely worked at the track.

Bump for these, that's a real good deal, those go for over 2000+ brand new.

If it wasn't for our darn California smog laws I would greatly consider those.

Those will produce some nice power.
