Factory roller 360 and 308 head questions.

I have a set but they are the 547 or something like that. They were from MP and have no air hole in the exhaust ports and 2.02 valves.

My heads were 69cc before I had them milled .030. That made them 63cc.

I am with you about the newer rocker arms. I believe the shafts are better for higher rpms. Just get the iron adjustable rocker arms and push rods.

I am very happy my 318 has them.
