.my main question is are the 1- heads OTB a good candidate for this application and woul;d a full port job be of any benifit.


as a racer you know porting is always good to go faster.CFM=HP X atmosphere ratio[14psi = 2x HP with the same temp]just a guess but i think it would take 20 CFM porting to lower the boost psi 1 lb and that may be 20*F per lb psi.just trying to giving you things to think about.
