I doubt your putting out the spark.  I've run 22 psi
through a stock MC motor without any problems.  Now 20
psi with a big valve head, 272 cam and a header gave
me a few problems that may have been spark related.
Either way the Crane Ign and HD valve springs cured
the problem.

Can you see what your mixture is doing with a AFR
gauge?
