Lowest CC for adequate PTV clearance??? I am looking into getting TFS As Cast 220 heads and running a 231/244 .630"/.615" 112.5+2.5 cam. I want to get 11.5:1 CR. I was looking to run the TFS 220s with 61cc chambers. Is this possible with an .040 gasket to get the CR i want or will I have bad valve clearence. This is a stock LS1.
