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.

SHIT. too late already bought em...
Oh well ill reuse the stockers anyways.
and resell the Stage8 ones...

What do you guys think about O2 sensor extensions? needed?
edit: for headers that is....

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