Vtec Problem

OKAY, I HAVE A 1991 INTEGRA. B18A BLOCK, ITR PISTONS, B16A HEAD, ITR CAMS... I SENT THE HEAD OUT TO HAVE IT RERBUILT. INSTALLED THE HEAD, AND IT RUNS GREAT W/O VTEC. WHEN VTEC ENGAGES, I HEAR A CLICKING FOR A SPLIT SECOND??? I TOOK THE CAMS OUT, AND THE ROCKERS LOOK GOOD. NOT MISSING ANY PINS OR ANYTHING... VTEC KICKS IN, BUT DOESN'T PULL AS HARD AS EXPECTED. PULLED THE VTEC ECU, PUT MY STOCK ONE BACK IN WITH A VTEC SWITCH, AND ANYTIME I FLIP THE SWITCH, IT MAKES THAT SAME NOISE(SO I KNOW IT'S NOT THE ECU). I DON'T THINK IT'S OIL PRESSURE, BECAUSE EVEN IF I KICK IT ON AT 5300 RPM, IT STILL MAKES THE NOISE. I RULED OUT THE ROCKERS, SWAPPED THE VTEC SOLENOID, I DON'T GET ANY CODES EITHER... ANY HELP WOULD BE GREATLY APPRECIATED!!!! THANKS ANDY
