Manufacturer profile information
Checking heights are shown with the duration figures. Net lift is the net valve movement specified by the manufacturer, while cam lift is listed separately. IVO/IVC denote intake valve opening/closing and EVO/EVC exhaust valve opening/closing. BTDC/ATDC mean before/after top dead centre, and BBDC/ABDC before/after bottom dead centre.
Installation and profile selection
Confirm the exact engine version, valvetrain design and the modifications required by the profile. Check cam timing and valve-to-piston clearance during installation. Springs, lifters and other supporting parts mentioned with a profile are not included unless the profile explicitly states that they come with the kit.
