1959 Dodge 361 low deck engine.
It's been fully reconditioned.
I'm just dong a pressure check on the coolant system.
I have coolant leaking past the front two exhaust manifold bolts on the generator side.
Has anybody ever heard of this before?

Yes, the exhaust bolts go through to the coolant. All of them do. So it's amazing that you only have 2 problems. I recommend taking them all out and using hi-temp silicone or other sealant on the threads before inserting them back in. Drain the fluid first, of course.
