Is the 3H5 cylinder head compatible with a 2H7 motor? The cylimder head I ordered comes with cams, valves, and shims already installed.

No, but that's the short answer. Need more info to elaborate.1980 XS1100G "Dolly G" Full Dresser (with a coat of many colors

Sometimes it takes a whole tank of gas before you can think straight.

What info do you needComment

No, don't do it, the compression will suck unless you change the pistons too, if it was the other way around then yes.2H7 (79) owned since '89

Well here is what I'm dealing with.
1. 3H5 motor with a destroyed piston and rod as well as a useless the cylinder head.
2. A 3H5 cylinder head on the way via ebay with valves intact
3. A 2H7 motor with all good pistons but no cylinder head
So I'm trying to figure the best way to get a complete motor. If the 3H5 motor will not play well with the 2H7 cylinder head then do I have to split the case to replace the rod that holds the piston?Comment

It will be fine. Just not as much compression. I run a 81 head on my 78 runs fine.80 XS1110 SG, RD400Comment
