Part of the reason I'm asking because putting my motor togeather, I'm aware of the cost of dissassembly. Pulling the head, $30 for a new set of head bolts and $180 for a top end gasket set. Pull the pistions and I need a new set of rod bolts, pull the crank and it's flywheel bolts and main bearing bolts, plus the cost of a bottom end gasket set. Pull the head requires pulling the cams that involves a $1400 special tool made by an 80 year old machinist in Bavaria. Otherwise the loads on the hollow cams will break them. So you can see a rather large bond may be required to see some of these parts.
