I wish I would have had the time to check them on the bench. I'm sure the chamber porting I did picked them up 10-15 cfm up to .500 lift.

My customer added up everything when he picked it up and said he had 6400.00 in the build including carb to pan and headers plus everything we did and dyno testing. I think he got more than his moneys worth considering the cost of the heads new and they were new.

Cam was only thing holding this combo back IMO..
