Debating Cams
Lift is not as important as duration when it comes to big lift cams!!!
.640 lift ain't no deal on a 233 intake duration.
Think about how the engine works... you only have piston to valve clearance issues when the piston is at top dead center.... you shouldn't have any issues running the TRAK cam on stock heads.
Only reason I could think of to avoid the TRAK cam is if you want to avoid the 921 springs ans shim setup.
