Yes I have bungs welded into my pan. 4 of them to be exact. Did the saem thing on the Valiant and I use -8 lines.

I will keep an eye out for some rockers. I ran the T&D common shaft set up on the Valiant and they worked great and do not require any additional machining to the heads like the individuals do. They have thier limitation but not until you get inta crazy springs and cams.
