Studs Or Reuse Stock Exhaust Manifold Bolts?

[Moparriggan]

Installing my exhaust manifold and turblower tomorrow.

Should I reuse stock bolts with only 50k miles on truck or purchase stage 8 lock bolts or studs?

Your suggestions.

Thank you!!

I would go with ARP studs and bolts and not reuse the stock bolts.

Also have you gone to studs for the cylinder head?

Yes ARP 625s on head.

I am good with your recommendation of ARP studs for the exhaust manifold, but how in the heck do I keep them from backing off?

I have used loctite 272 before and has worked good for that problem.

I used the Fleece/ARP studs.

Had to tighten a couple after 500 miles.

I recently re checked them again and they hadn’t loosened at all in the last 35k miles.
