Thanks for the recommendation but I am determined to get my car to an 11.5 or better with the MP 509 cam.


I am wondering....how much do you think I can gain by just having the heads milled vs. milling the heads and some light port work? The guy I know said he would just do a gasket match and clean up the bowls under the intake valves. He has a flow bench and said he would give me numbers before and after the work. I remember reading a long time ago that these heads are very good out of the box. I am just wondering if the porting would be a waste of time and to just worry about bumping up the compression?
