And for the grounding of the heads it's ok to butt heads, just don't do it with a butthead

I dont want to get into pee pee match but this is coming from some of the fastest in the business that have experienced the problem that high output ignitions can provide through bad grounds.

Many of the wiring system suppliers (Painless, Ron Francis, etc.) recommend against using the frame as the battery ground, too many joints that might not be making good contact. They recommend running a ground cable (same gauge as the power cable) directly to the block then another from there to the body. The INTERNET, the MISinformation superhighway
