Jim,
Being just North of 12:1 is a high calorie diet for runs to the DQ. What fuel are you thinking of?

- I had Muscle Motors go through the 452 heads that came with the motor home, upgrading the valves and springs, some bowl work and milling to 80cc. Based on my math, with the Fel-Pro 1009 gasket and figuring in 4.5cc for the Icon valve reliefs, this will put me just North of 12:1-
