Is it true that heads off a tpi engine flow better than heads off a carbed engine? If so, would putting heads from a tpi 350 on my carbed (4bbl) lg4 be better than tpi 305 heads? Thanks, just wondering.

 

If your car has a 305, don't put 350 heads on it or you will loose compression because of the bigger combustion chambers. The LB9 heads would be a good choice, if you want to put TPI heads on, and I have a set of them if your interested.
