L92 stroker not working properly

when you look at the dyno graph you'll see that the horsepower hangs from 5300 to 6600. I've seen other dyno graphs that pull to 6100 and then start to come down. one the first pulls the throttle body was only opening three quarters of the way. once we fixed that it only picked up 10ftlbs of torque, horse power remand identical and again hung from 5300 to 6600.

The motor has
ported L76
L92 west coast cylinder heads
HK engines 418ci
Kooks long tube headers
90mm nick williams

Any help will be appreciated
thanks,

i think a carb style will kill the bottom end. the only other one out there is the fast. but its a lot of money to find out its not the problem. damn those gremlins.

its making power but it should pull to 6100. not so worried about the numbers just want it to run right. looks like its going to cost a lot to find out whats wrong.
