What heads are on it? DOAE heads? If so, how can you up the Compression to 11:1 and be safe with pump gas, VIA the "Quench" area of the head?
Thanks!
Jeff
Jeff,
My CR is only 10.3:1. My heads are '71 Torino open chambered heads. I would not try to get to 11:1 on a street machine with pump gas. It was someone else who had 'Quench' heads.
