STRT has 2.02/1.6 valves, 3/8" rocker studs, and 1.250" OD valve springs for a hydraulic flat tappet camshaft. FLAT has 2.02/1.6 valves, 3/8" rocker studs, and 1.465" OD valve springs for a solid flat tappet camshaft. RACE has 2.055/1.6 valves, 7/16" rocker studs, and 1.550" OD valve spring for a solid roller camshaft. We will need to know the lift of your camshaft when ordering these. The RACE assembled heads will also take 1 to 2 business days before they will be shipped.

The 200 runner Sportsman 2 head does not require an off-set rocker arm even with a roller cam. You will simply use standard rocker arms. With increased rocker ratios it may be necessary to elongate the push rod hole slots.
