So doing a camshaft upgrade for this season and I'm debating on changing cylinder heads also. My current heads are 781 large oval port with 219/188 valves 115cc chambers with alot of port work done to them best of my capabilities motor is a 10 to 1 static compression 496. So I have another set of heads with 98cc chambers (427 TD heads) large oval port with 219/188 valves that were installed by a friend no port work tho which I could do and would put this motor right to 11-1 static. So my other friend has a new set of bare patriot heads 320cc (rect. Ports) with 119cc chambers which with a thinner head gasket would still keep me at 10-1 static ,he has good quality parts for these heads and I can get them for a pretty fair price. I have strip dominator for both oval and rectangle port heads. Car ran 10.20s last year on 150 shot of spray that was rich 11.2 on the AFR gauge . Goal for this year is to be in the 9s
