In the past my builder used clear 100% silicone. Lately, on my own builds I've been using Right Stuff. Pans and VC were fabbed aluminum with billet flanges. We also used clear silicone in place of header gaskets and as a thread locker on header bolts. I now use MLS header gaskets... much easier to work with and last forever.
Blykins makes a good point below regarding pick up clearance... never thought of that as I've always run drysumps.

To echo some of the others' thoughts, I too only use cork or nitrile rubber multi-piece gaskets on my small blocks. I've had way too many issues with 1-piece gaskets. I smear a layer of Right Stuff down on the block, put the gasket down, use Right Stuff in the corners where the end gaskets meet the sides, smear another layer on the gasket, then lay the pan down.
It's also very helpful when you can do it on a stand without the harmonic balancer or flywheel on, as you can see how the end gaskets move/remain in their spots. I've had some of them move when the pan gets bolted down and had to redo them.
