In refinishing mine...found a crack on #2 mounting flange going out into the the casting. So...looking for a servicable/useable cast exhaust manifold in UNCRACKed condition. Blanking plate not needed, I'll swap out. But, preferably with all the studs in decent condition (and did I say no cracks?)
Going to swap out when I replace lump with the cast unit; the header I purchased fouls the shift tubes coming back, so had to apply percussive maintenance to get it to fit (the measurements for the center rose joint etc were fine...just that the header was not built properly and stood too far out from the block...).
TIA.
