Car was originally a 273 car now a 318. I assume they are the original manifolds. I did a leak test and it's mostly coming from driver side nearest the fire wall. I started spraying the nuts and bolts with pb blaster for now.

Not sure but that could be one of those Flat Flange driver's side exhaust manifolds. Otherwise if it is a Bell Flange it could just be loose too.
