I have a 6 pack intake for my small block. Everything is brand new. To start with I used the Fel-Pro gaskets in the gasket set. They were roughly .040" thick. They leaked at the bottom of every intake port. I bought a set of Edelbrock .060" thick gaskets. Still leaking ( pulling oil in from the lifter valley ) at the bottom of every port. I need to check the angle of the heads vs. the angle of the intake. I have an degree angle finder like you would use setting up driveline angles. And also an adjustable angle setting tool. What would be the best way to go about doing this?
