KB-107 or the Speed Pro/Federal Mogual 116 Skug. Both are hyper U slugs. Decking of the block is needed.
Use a .050 gasket. Cometic can make them for you if there not on the shelf.
That should drop you so we’ll enough.
I run my slugs at zero deck and a .038 thick gasket. That’s just under 11-1 (IIRC, it is 10.8-1) and my mildly milled heads bring it up to 11-1 on the nose.
My cam is a large solid Comp 294S. It works on pump 93 just fine.
