If you are just breaking it in, buy the cheapest set of headers you can find and some collector mufflers to do that. Then put your coated headers in and hook up all the neccesary clutch linkage when that is finished. You certainly don't want to buy a GOOD set of uncoated headers and then have to get them coated.

Heddman was the only header I could find that really did work with my Jimmy and the SM465.

But the Corvette rams horns are a better solution if you are less than 400 hp...
