Having installed and transferred a number of tapered cylinder engines in the past 24 months, probably a dozen or so engines, I take a very simple route. A stock Vans baffle. I drill a second hole on the flange for the safety wire that is close to the cylinder base. This puts 2 holes in each flange. One in the middle at the stock hole location from the factory, and the other, a new hole, couple inches closer to the cylinder base. I use both holes, and safety wire, to pull the baffles together underneath. This gets ~90% of the coverage needed. Then simply using a flashlight, and high temp rtv, I fill in the gaps using a popsicle stick to get the rtv where I need it.
