What exhaust manifold bolts?

[sahls01gmc]

I'm fixing the exhaust leak, and figure I should replace the bolts. Of the 6 on the passenger side, 1 had broken off so I imagine the others are not too far behind.

 

Can I use a standard Grade 8 bolt, or do I need to stick with a certain type of bolt?

 

This is by no means a hot rod truck, so I wasn't looking to go buy the top of the line ARP or equivalent bolts. Just need something to last another 300,000 miles.

That will work fine - just be sure to use some type of anti-seize compound on the threads before installing.

Thank you! That was my next question. What do you recommend?

I always used Permatex Copper. Before that I've used just about everything - at one point I was using a 20 year old can (at the time) of John Deere never seize from back when they were building snowmobiles.

 

I've had great luck with all things Permatex these days however.

 

This is probably 100x more than you need, but this is what I use: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dautomotive&field-keywords=Permatex+31163
