You have the big crankcase vent in the left hand side of the block
run to your catch tank too? Having that plugged or too small (maybe
a small fitting in the fuel pump cover plate) has been a source of
pressure build up in my experience. Pulling the plug in the hole for
the big vent so it can be re-installed with the engine in the car is
a major PITA.
