Our record for this one only shows a single catalog appearance, tied to the 1980 model year. We don't have additional detail on castings, port configuration, or which specific engine it was cataloged against beyond that year, so give us a call to confirm it matches what you're pulling off the bike before you order.

If you're rebuilding a top end, this is the core piece the valves, guides, and rocker gear all mount to, so it's worth double checking against your existing casting and stud pattern before swapping one in.
