This is why you should port match your intake (pics)

Pic is Weind, about 3 years old I think... Crosswind wasn't this bad but antifreeze seaping out the rear of it was and the machining was just silly bad.

A few years ago I ordered a new Weiand Stelth for a street 360 I was building. I could only get 3 of the bolts started, all the rest of the bolt holes were off some by 1/4". The casting was so rough that I also cut my finger on it. Sent it back to Summit in exchange for an Eddy performer.
