....me think I'm loosing my mind !!!!..doing a gasket replacement on my 85 V-6, and the PM Blaster does help to a point, but broke a bolt on one stud ( below # 5) and the spring/bolt on the crossover..... getting the heat shields off was a challenge. Cleaning parts and using VHT to clean up appearance...replacing O2 senor, bolts, EGR gaskets , plugs and wires. QUESTION????...when replacing parts, should I use LOCTITE RED (high heat) on all the exhaust bolts or is anti-sizing good enough ???...should be done by Christmas

I'd use anti seize.
Says "Temperature range: -60°F to 1600°F"

The Loc Tite I looked up as "red" said "temperatures of up to 450 degrees F" on an exhaust manifold you need more like 1500 degrees.
