Have you ever encountered any like the problem im having them?

According to another post my valves are within spec but imj still having problems.
I still have a possible sticking valve / or just a straight miss , im getting suck back at the exhaust and a slight miss, i have of course replace all sensors, and cleaned everythig, the only item i havent replaced is the o2 sensor. any idea, should i just attempt to adjust the valve's anyways or what idea wold you have for me on this issue. ill list below exactly what i have done

The following was done to attempt to correct a slight miss at Idle only

Head Has 5K on it, it was a completly redone head

Removed and cleaned Throttle Body
Replaced TPS
Replaced IAC
Replaced RSR
Replaced Dist
Replaced Coil
Checked and Reset timing 3 times to 0 and then 10 no diff
New wireharness 80K ago
Replaced Fuel Pump
Replaced Fuel Filter
Replaced Turbo Hoses Inspected Others
Replaced All Vac Lines!
Cleaned Injectors
Cleaned Plugs
New Wire's
Replaced FPR

I am thinking at this point my new wires could also be bad so im going to swap them out once more in hopes it will fix my problem.
