I was talking with someone a few weeks ago about a possible cam purchase....... and he said he plans of using those heads.
He mentioned that they revamped the ports a bit.
they did more than “ revamp” the ports a bit.
Vic spent a lot of time testing and working on them. Couple years actually, been on and off benches a bunch..valve job testing, yada, yada.
They will be capable of running 9’s on a typical bracket A body stroker deal.
The set that i know of already running go 132 on pump gas in not good air at 3175, and there are several issues yet to be ironed out with that combo that definately is affecting ET.
