If you have spacers under your cylinders instead of cut domes or cut head for the stroke, then your port timings are out of wack.I would not use spacers.imo.Also what is your compression? If it is to high then that will kill your over rev.You need to shoot for about 180psi for a race gas motor.

the comp isnt too high and its running right now on pump gas just dont know too much about these wondering why the powerband isnt kicking in

i just did a 4 mill and with a very thin basegasket and that was the only way i could get the port numbers respectable. with a spacer plate i think the transfer numbers would be nutty.; what i ended up with was 130/198* and it runs awesome.

are my jetts right or should i go different?

Just a wild guess, but if you're revving out but getting no power, then it's possible that you're too lean on your jetting. Since you're running a boost-bottle, you might want to check the intakes for any air leaks from cracks.
