351W (stroked 392 RDI) with Edelbrock Victor Jr. cylinder heads.

Questions:

What plug do most here run in these? I'm running an MSD 6AL ignition.

What SIZE are these plugs? Are they 5/8" hex or metric?

Looks like I need a thin wall socket. Who sells a good one on-line with a flex head?

Thanks!
