Some quick answers
I'm running the Stg. 2.5 5.3 heads on my car so what ever they come from TSP
I think the compression is around 10.8:1
The valves are 2.02/1.57
I didn't have to flycut the pistons

I got the PRC 1.0 from TSP.Didn't flycut. Don't know about the compression. Don't think the heads were milled. Just make sure you measure your valve springs good. When mine were put on the first time the springs weren't measured good and my valves were tapping the piston. Had a 1/4 moon. Valves were still good. Remeasured everything and they were good after redoing them.
