Timing Chain Noise

Chain was tight to the sprockets when installed. Old chain had quite a bit of slack when removed. I just went back outside and turned it over a few times again. I do not like the sound coming from the timing gear set. Set is a Comp Cams double roller timing chain. I will open it up tomorrow morning and try to figure out what the issue is. Timing marks are lined up within 1/8 " from top to bottom sprockets. I tried three times to get em perfect and this is as close as I can get. distributor rotor is pointing at #1 cylinder, on compression stroke. Everything seems to be lined up from what i can tell.
