If it was my decision on your parts I would send the heads out this coming winter and have them CNC ported and have the 2.25 intake valves installed to allow more RPM from then on work
Are you sure it isn't running out of fuel at the 1000 mark?
I've seen so many drag cars( of all brands shock) that have those issue with no other signs of lost of fuel delivery work
If you can't jet it up enough to slow the MPH down in the 1/4 mile your running out of fuel, not fuel pressure, fuel volume scope work
One of my newer Holley HP 1050 Dominator carb. had one .110 needle and seat in the front or rear and the other one was a .120 seat, I could not jet that carb. up enough at the 1/4 mile track to slow my old pump gas Duster down confused Once I changed it to .120 on both fuel bowls I could work shruggy
Lots of gremlins out there runaway shruggy
