Took my head off, now what?

Tore down a the top end of a "junk" 185. The head, bore, everything looked great-clean and shiney. Here's the question, whats the diff between the 185 and 200 heads? What will I have to do to make the 185 a 200? I have a spare cylinder for a 200, figure I'll need a new piston, what about the rod and crank, are they different too?

The only difference is the piston and cylinder, everything else is the same.

If you can get a 200x head and cam you wil get a little more hp. You will lose the compression release though.

Most of the parts from these old honda are preaty much intercangable as long as the engines are similer.
