A Snake - Good point!
My edelebrock manifold had to have over $200 worth of machining to mate up properly to the Edelbrock heads!
It sounds crazy but things that are supposed to be plug & play simply are not always that way and I would have not caught the error if I had been assembling the engine. Conversly, as mentioned prior I too have no leaks on the top side (even in that peske area around the Intake/head/block) but as mentioned everything was measured - corrected - blueprinted, oh, I also paid $11k for my REBUILD so it better not leak!!!!!
