One obvious thing will be more valve train noise with solids. Once you get into the expansion rates of aluminum hyraulics are desirable. Ask anyone who tried solids in a panhead. I sure wasn't a happy camper with it.

Below is what I know of who sells them, and "maybe" who is making them.
These are sold stating large port, so not a 100% OEM match.

These guys sell them in the states.

These guys sell them in Germany

I read somewhere that these guys make them, however aluminum KH heads aren't shown on their site.

For the best deal on bike parts, call Calif Phil
