the reason i ask is because alot of the headers you buy will supply new bolts but ive heard that with pacetter you might want to use new ones, if you bought ARH, Kooks your for sure ok and OBX i think they are ok too but not exact.

What size and length are the stock manifold bolts?

Can you just pick up some grade 8 bolts at Lowes and use them?

I just bought a set of OBX headers and CANNOT use the bolts they came with.
These bolts are garbage.

Any Sugggestions?

I've used the stock ones, three times now. Clean them up with a wire wheel and toss a dab of anti seize on the threads.

i believe they do require the use of an O2 extension. You can go dig up the info in one of the OBX threads.
