I built up the courage (thanks to a couple of JD's) and decided to attack my valve covers with the TIG. I had a spare set of LS1 leads lying around so I decided to recrimp the coil end of the leads onto my cut down MSD's. Its taken me an hour to do 2 leads
Welded the other cover but a weld cracked 6" away from where I'd been welding so had to play "chase the crack". I'll need to repolish that cover again, but it's as good as done now.
