LEAN POP THROUGH INTAKE!!!!!!! HELP !!!!!!

[5ohCOUPE]

EVER SENCE I PUT CAM, HEADS, AND INTAKE ON THE CAR IT HAS AN INTERMITTENT LEAN POP AND SLUGGISH OR A LEAN FEELING PART THROTTLE TAKE OFF. THE TIMING IS AT 14, I HAVE GOOD FUEL PRESSURE, NO VACCUM LEAKS, ALL SENSORS ARE GOOD. I HAVE NEW O2'S, NEW MASS AIR SENSOR. THE THING RUNS GOOD AT WIDE OPEN THROTTLE BUT SOMETIMES IT JUST FEELS REALLY SLUGGISH AND IT WILL LEAN POP THROUGH INTAKE ON PART THROTTLE. I HAVE 73 MM C&L AND 70 MM MAC TB. ANY IDEAS WHERE I CAN START ????
