TSP PRC stage 3 6.0l head flow #'s
Bought a set of stage 3 317 castings from TSP awhile back. At the time there were no flow #'s for them on their site. I was told My heads would be flowed before they were shipped out and a flow sheet included. Well guess what didn't happen. 
Not trying to bitch just giving the full story. I was very pleased w/ the service from TSP in spite of this and a mix up w/ comp. They cleared everything up and shipped all my parts out once we found out comp dropped the ball on the cam order.
Anyway I took my heads to my engine builder to have them flowed. To Know for sure what these heads flowed and to get some exhaust #'s.
