I have a NOS Smartech .29 nitro motor. It was still sealed in a bag before I opened it. For whatever reason it does not have a head. If I cannot find the genuine replacement, I am trying to figure out if there have ever been any other manufacturers of a .29, that I could match the bore and headbolt pattern? Even if used, I don't mind.

I tried a .25 head I had for kicks but of course its too small.
