I can't get the darn thing to seal. It doesn't help that I destroyed my threads getting a snapped stud off of the rear manifold /crossover.
Ordered OEM bolts and a felpro donut gasket.
It still seems something is missing.
8 mm bolts/studs. Gasket. Heat shield.
Weren't there square nuts somewhere in the equation?
Weren't they welded to the rear flange?
Well they're gone now.
