Thanks for the replies and suggestions.
I am having this work done by a mechanic friend and when I went to see him the other day about it he had the engine mostly back together - the head was on in any case so no magnaflux or milling. He is going to remove a couple of the soft plugs to flush the water jacket out as the crank and pistons were still in the block. He did have a question about the front engine plate and gear alignment. The gasket kit came with two different gaskets for this and we are both guessing it is to establish correct gear engagement between the primary and cam gear. The manual I have does not address it and he could not find any info on it either. Anybody have any comments on that?
