Hi Eric. I have no idea how to post pictures on this forum.
There is nothing special about the intake manifold. It is like any other you have already seen. Same for the exhaust headers. Independently both bolt on the the head fine. The problem is when the headers are bolted on to the head, there is no room between the tubes in the headers to fit the rear intake manifold. It is just the routing of the header tubes that causes the problem. Whoever designed them, did not consider that they could be used together with DCOE Webers.

I'm trying to find out if anyone on the forum knows of a header that works together with the DCOE Webers. As I said, if nothing comes up, I will either try to modify the BHP header that I have or use the cast iron FI exhaust manifold that I know fits. Both options will be challenging, as my welding skills are terrible and finding a competent welder around here is almost impossible.
