exhaust bolt sealant

[68 A]

hi,

Wondering what everyone uses to seal the front and rear exhaust manifold bolts. I use a high temperature sealant, but every time they will seal but when I tighten them up at least one of them leaks and starts to steam, and of course lose coolant.

Thanks,

Steve

Make sure threads are dry and clean and allow 24 hrs before filling with coolant
