I did my head, intake, cam, piston swap over the holidays and everything went great until i get to the very end, the upper intake. I have a trickflow upper, a trickflow throttle body adapter for it, trickflow tall valve covers for my rr's, and a trickflow 1" spacer. With that setup the tb hits the valve cover and cannot be properly attached, which leaves me stranded on the project. I was wondering if anybody has a similar setup and has found a way for it too work. The only thing I can think of would be to try a edelbrock tb adapter if it would fit my intake or to put a 3/8" spacer above my 1" spacer, which seems stupid. My last resort would be to notch the valve cover and tig it.
