Good set but head gasket weird
All together this set is good. It doesn’t include the two rubber o rings for the side channels and the head gasket fit on a bit weird on my 1982 CB650. It wasn’t a perfect match but I’m hoping it solves the oil leak problem.

GREAT...Make sure you know which head gasket you need - there are 2 different versions to the CB650!
Good Product!

No Leaky
What can I say? I replaced the base and head gasket and they aren't leaking. The kit I was supplied was missing the 11x2.5 dowel pin o-rings (around the dowel pins between the base and the cylinder block), so I had to reuse the old ones(The kit list appears to have the oil control valve and dowel pin o-rings sizes swapped). The important o-rings are between cylinder block and the head are included. FYI - I used the gaskets dry.
