exhaust manifold studs... WHY?

[Wilson]

Why are exhaust manifolds bolted on with studs and nuts, and not just bolts??

Would it matter if I used a few 8mm bolts instead of the studs as I'm missing a few!!

Urgent answers are appreciated as I'm doing it now, and I'll keep popping back to the PC to look for answer!!!!!!

Thanks

i would and have in the past but cnt remember what size they are tho
ive got 2 snapped in mine so will be doing them very soon Daz

they are 8mm, but is it OK to use bolts instead of studs and nuts...??

sorted i,ll try remember for when i do mine how long are they ???

only snag is lining up the gaskets unless theyre still in one piece get new ones Daz

as long as they dnt crossthread when they go in no probs just match the stud threads to the bolts
