have you actually made the butterflies any bigger or just welded bigger tubes to them?! they won't flow much/any more than the narrowest point on the inlet tract.

the bodies tapered from about 35mm to 50mm so i cut the taper off so there 50mm all the way then extended them with tube to the manifold.the guy thats doing my head has put 50mm ports in the head to match the bodies. this is never gonna work lol
