I seem to remember that a 2 piece Ford Viton lip seal set up was used back in the day? I've got one somewhere in a pile of Pontiac parts I bought a few years back. I also still have half a dozen of the old asbestos type rope seals, maybe I'll try one of those -the Graphite rope seal I last used ,leaked a tiny bit.
Want to sell a couple of those asbestos seals ?

I think the one piece BOP seals only have issues on blocks that have been align bored. One you cut the cap it shrinks the seal part of it while the main bore is perfectly round. Hard to see a way around it. I have a one piece and a graphite on the way but would rather use the cancer causing stuff.
