I tried to find out the same thing but all i could muster up was a maybe...i don't think it will work because of the H23's increased stroke, I believe the higher compression dome on the type-s pistons will hit the valves if used in our H23's. Gude seems to be an excellent company I wanted to get their head package to, but instead of type-s pistons you could use something from JE, Arias, or any other reputable company.

hope that helps
