I should start with this is my first experience with Y-blocks. I have a 55 272 that I had bored to standard 292 spec. I bought a 4 barrel manifold ECZ-9425-B. When trying to fit it, it hits the lifter valley cover and will not sit flush on the heads by about 1/4 " at the front. this is with all the gaskets in place. What is wrong?
