Haven't tried them yet, but how do they'll dowels stay in? Do they have to be pressed in?
Thanks

They are a firm but not overly tight interference fit. Tap them into the crank flange with a brass hammer with the crankshaft removed so you don't hurt the babbitt.

The part noted above goes aft (clutch side) of the flywheel, not between the flywheel and the crank flange.

A little Loctite Red can't hurt. The bond will break when you hit the backside with a small punch/hammer.

The dowels need to be a line fit meaning the holes and pins have the same diameter to the 3rd decimal place. The close fit is for structural efficiency, that is to assure that the pins transmit most of the engine's torque in shear.
