Using factory nutted studs on stock exhaust manifold collectors
So whats up with the factory exhaust collector studs that have a permanent nut midway on stud that bottoms out against collector surface then a second nut thats tightened down onto the stud end.
Is there any reason just plain old bolts cant be used to tighten the collectors up with?
I broke all but one of the nuts off when trying to loosen them all even after soaking them in PB blaster. So instead of buying all new GM studs at about $5 a piece im thinking why wouldnt a .30 cent bolt work just as well. The picture below the stud/nut are actually in the opposite direction for the picture and I didnt notice it.
My weekend project...What fun!

I only broke one stud on the passenger side. I through drilled it and used a 1/4" stainless nut and bolt.

I think the frozen nut problem lies in the fact the GM nuts are self locking and are hard as hell to get back off after many heat cycles. I heated one up wit ha torch to see if that would help and it broke off as soon as I turned it so it didnt like a torch put to it at all.
