I am running the same head,the intake ports are 1.8 inch instead of 1.7 for the street version.
My friends shop is going to finish the valve job & install the springs, but I need to get a camshaft first before the springs. I think Mike told me my head flows around 318cfm in. & 220 on the exhaust? That was with no back cuts on the valves.
I will have it flow tested @ my friends shop. Will be testing different angles for optimum flow & get back w/Mike on the results. Maybe have a little more porting done?
