Interesting that a "wedge" shape has some quenching where this one does not. Algon did make a wedge shaped chamber and it was not as effective as the Wayne or the Horning which had an oval camber. The Skinner, which this one is, was designed after the Chev V8 was in production. This also allows for a spark plug to be in an "over" position instead of a "side". I do know that these heads love nitro methane and not too sure about the wedge.........Good Luck.
Good price on the head but missing too many accessories.
