McJack's ceramic coated headers?
Found this at www.mcjackscorvettes.com
Details are "slightly ported", fits 86-91, $495.
I have seen his used car ads before. Is he just a
artist or the real deal? He seems like quite the huckster. His models are quite nice though!

But... they 'look' like stock shorty GM headers that have been chromed or coated.
We all know how putrid the things are in the flow department.
They do look good but I'm not too sure you'll get 425 bux worth of extra performance out of them.
Goodlawd, his models DO LOOK GREAT!!!!

yeah, those are stock shorties. I'm guessing he has a core charge too?
GM quality control is crap on these (at least on mine) so i think a little porting and cleaning up is worthwhile on em. I noticed a louder exhaust note afterwards, but can't speak towards any gains.
