In case anyone is wondering as to the outcome of all of this I got my engine back a few days ago (over a year later) as a completely rebuilt short block assy.
New pistons, rings, liners, valves , guides etc and with the crankshaft/flywheel/clutch assy balanced. The pistons and rods were statically balanced.
In spite of me spending hours cleaning out and re-tapping the head stud holes the re- conditioner drilled out and helicoild the whole lot.
Nothing like doing the job properly and surprisingly not too expensive.(for the helicoils that is, I won't mention the cost of the rest of it.)
Warm regards to all.
