CYLINDER HEAD
Cylinder head for the engine top end, listed under cylinder head and rocker boxes, also known by the older E8781 number.

The cylinder head sits on top of the barrels and carries the valve gear and rocker boxes, sealing the combustion chambers and giving the valves somewhere to seat and operate. Our catalog record for this one spans several years of listings, but it doesn't spell out a single model fitment beyond the general engine-top grouping, so don't assume it interchanges across every variant without checking.
If you're sourcing one of these, bring your old head or your frame/engine numbers to the counter so we can confirm it matches before you buy. Cylinder heads can look similar across model families but differ in port shape, stud spacing, and rocker box mounting, and the catalog entry alone doesn't give us enough to guarantee a match sight unseen.
