First scenario is i ran the car with my O2's at 744 with no knock retard, and ran 12.1 @ 114mph. but the car felt slow compared to runs on street. I pulled plugs @ the track discovered one bad plug, did a blow by test and was leaking into radiator. So i installed new head gaskets and now the car has 14degree knock retard @ 750 02's with no other changes but head gaskets and increasing of alcohol to richen up mixture, my fuel pressure is 43lbs with vac line off recommended by Eric Marshall who's chip i have with 20degrees of timing @ 3rd gear. All scenario's are ran @ 24lbs of boost. Would be greatley appreciated your input on the situation and any suggestions you might have. I plan on taking the car to the track on saturday. Thank you
