Here's some pics of my headers being prepped. Notice the cracks in the collector. Also the original air pump hole weld-ups protruded into the headers. I ground out the welds inside and out and had one of my guys Tig the holes shut. We checked them for leaks.

Here's my headers after Jet-Hot ceramic coated them. We built a jig to hold the Headers and a jig to control the Collectors before we welded the Sniffer Tube Bungs on and the Air Pump Holes shut. Sorry that I'm posting the info "Post" Ceramic coat. The aluminum plate on top of the jig (with the pin sticking into the Sniffer bung) was used to line up the angles on all the bungs.

Word of warning for anyone dealing with Jet-Hot Coatings. Make sure you remove exhaust seals, doughtnuts and anything else you don't want coated. Make sure you tape or plug threads also. They'll coat right over anything! I asked them why they didn't cap my Sniffer Bungs (yep, ceramic coated threads) and they said they coat everything unless you tell them. They also said they call to check (which never happened). They did say they would pick them up and fix them. It cost me $42.00 for a special die to fix my bungs but I did learn a valuable lesson! No biggie! Just thought I might save one of you from the same mistake I made!
