All good. Thanks for the info, I have had it running for a month or so now. Fired right up and didn't even have a crossed plug wire, :).

I pulled the head off with the manifold attached. Changed springs, valve seals and pushrods on both heads. Used 50ft of weed eater wire and a grease gun tube to feed it into the cylinder to keep the valves from dropping on the other head. With the long plug channels it was a pain to try to use nylon cord. The weed eater wire was one of my Ah Ha moments.
