exhaust studs

[lynnboy021]

i was installing a rear main seal and while removing the exhaust manifold flange nuts some studs just keeps spinning and some broke off... can i use regular bolts or can i weld new ones? i really don't wanna take the manifold off..

DO it properly and extract broken bolts/studs

Otherwise it will happen again

Do not weld to heads can ruin all sorts of engine electronics
