The very best seals so far have been from KACO. They are a white silicon type material. For the o-ring inside the flywheel I find that ones in the engine kits are not quite right. Get it from the dealer if still possible. The flywheel to crank bolts are onetime items and should be replaced. Setting the end play is critical.

Right. Yes. Have read the gowesty article on those seals. Can't recall brand I bought locally. We'll find out. re: flywheel sealing surface.
At very least I find it very interesting that the seal actually contacts the flywheel. Unless I'm misunderstanding things.

Stuart: I get what you're saying but for me, learning to measure crank end play is something I'd like to do. Thanks for link to the gauge.
Maybe something similar
is available up here in Vancouver.
