Description
Natural finish. Bolt-on with stock style flat top pistons. 76cc high compression heads for approx. 10:1 CR (80"), 9.4:1 (89"), 10:1 (96") compression ratios. The port design allows these heads to outflow stock heads by a wide margin. This set-up can be used with up to .585" lift with TDC lifts of .252" intake and .210" exhaust. All heads can be decked .060" to increase compression but extra care must be taken when assembling decked heads to assure sufficient valve lift clearance. Compatible with fuel injection models and will take stock head temperature sensor. Heads come complete with valves, guides and valve springs installed.
