I am selling "Hedman Hedders" headers and Stage 8 locking bolts (no gaskets) off of my 1996 Chevy 1/2 ton. Should fit just about all vortec small block heads, but you might need to plug or modify the EGR plumbing if not the same as a 1996 GM 1500.
The bad - they're not flat at the mounting surface, if you don't want leaks they will need to be worked on by elbow grease or a shop that can deck them flat. The flange is a healthy 3/8", the mounting surface can be fixed without getting into the flange.
The good - they're only out of flatness by about 1/16 inch. No leaks at the welds/collector/etc, no issues otherwise. Surface rust is cosmetic only.
The price reflects their flaw, and the included $50 bolt kit should help as well.
