quality of casting on the manifold seems to be quite good, need better pics of a greddy to compare. i have yet to take my current stock manifold off to compare the gasket to the vulture plenum. i am hoping is close or spot on...don't really feel like grinding...
mine came with a so called stock throttle adaptor but was made completely wrong. i am having mine milled down as we speak. the thing i have an issue is that on the manifold, they haven't spent anytime milling out where all the bolts go so when you put a bolt through the whole, neither the head of the bolt nor the washer will sit flat...
