5.2 magnum exhaust manifolds.

Should probably state the engine when asking, but we guess "must be small-block". They will bolt to 273 heads and many use them. I recall reading of clearance issues on the passenger side, but each car may vary. Worst-case, you might have to use bolts instead of studs & nuts. BTW, I understand that intakes vary. I recall that 340 & 360 ports are taller.
