Is anybody running R&R heads, an HPI intake, and the SE Heavy breather? Just bought a Heavy Breather and can't get it to fit up. There is an 1/8" gap between the backing plate and the T/B, no big deal, I can fab up a spacer for that. The big problem is that the holes in the backing plate for the breather don't line up with the breather holes in the head. Also the head breather holes are bigger than the breather bolts supplied.
R&R now has their own A/C system that will fit and supply more power. They have also done a redesign on their cast heads so that other A/C's can fit right up if stock length cylinders are used.
