Racing Beat Holleys

Anyone mic'ed out a Racing Beat set up Holley for a 12a?
Exactly what size are the primary and secondary jets (sealevel)
and what size power valve?
This is going on a mildely street ported motor.
Currently got 57 jets primary. 65 seconday and
a #8 power valve and she seems to run on the rich side and
lacks a certain "Umf".
