Natural finish. Direct fit with stock flat-top pistons. 82cc low-compression heads for approx. compression ratios of 8.4:1 (80"), 8.9:1 (89"), 9.5:1 (96"). The chamber design allows superior flow over the stock heads. This set is compatible with valve lifts of up to .585" with lifts at TDC of .252" on intake and .210" on exhaust. All heads can be milled .060" to increase compression, but special care must be taken when fitting milled heads to ensure sufficient valve lift clearance.
