Includes one pair of exhaust flanges for the Buick Straight 8 320 hot rod motor (see motor applications below). These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel. P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then a light coated lightly with oil. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
Motor Application:
Buick Straight 8
320 cu. in (1936-52)
*more applications/years may work, verify before purchasing.
Ports designed to be used with 1 1/2” exhaust tubing.
These flanges are designed in CAD and are test fit to make sure proper fitment is achieved.

I like the fit and of the flange would be nice to include the right thickness in the flange so ya could bolt it up to the intake but an easy fix and they line up perfect
