All done. Thanks for the great advice. I neglected to order the valve cover gaskets so I will need to do that soon. Otherwise, it went pretty well. A couple things I noticed:

The screws holding the rocker arms in go in from the other way on the new cylinder head. Don't know why, they just do.
The original rocker arms did not fit on the new cylinder head - they were too snug. A little grinding (just a little) and they work fine.
The O ring where the carb goes into the cylinder head looks to be just a shade different size. I will have to see what can be done to fight potential air leaks.

Engine started right up and ran real strong though.

Thanks again for the good advise.
