    flycut pistons with afr /heads ?

    Hey guys I had someone tell me recently tbhat when I put my heads on I was susposed to flycut the pistons. I have AFR 205 heads and am running Comp Cams 588/581 camshaft. I have had it together for 3 years now with no problems. I recently found out I have a head gasket leaking into a cyl not mixing with oil. The engine did run up to red mark for tem/p once and I have been noticing some lifter noise lately. I am planning to pull it back daown and replace the head gaskets. I will check piston clearance again to make sure. Was just wwondering if anyone had run into this issue?

    what are the specs on the cam, and what cc are the heads? you will want to check the clearence, but if you don't have to flycut the pistons, don't do it because all you will be doing is dropping your compession ratio
