I've got K5 cylinder heads on mine, they have a little box that pipes the rocker box air to the exhaust ports (just before the headers attach) via a diaphragm or something, I think the idea is the vacuum on overrun pulls air in to burn off excess fuel and CO. Anyway it's too bulky to fit a curvy frame so i blanked them off.
