Milling 243 heads
I am just finishing up porting a set of 243 heads and I am wondering how much I should have them milled to bump the compression up with the 228/232 cam I currently have in the car. The previous owner that I got the heads from said the heads have already been to a machine shop so I am not sure how much if any has been milled already.
