Engine has a loud ticking noise while driving and at idle. Had comp 1.6 roller tipped rockers and swoped back to the 1.5 stock rockers, but the noise is still there. There is a noise in 5th and 6th gear, from part throttle to full throttle then noise goes away. Might be clutch chatter?

95 Z28
My engine build consists of a 355 with LT4 hot cam, comp cam chrome molley push rods, stock replacement lifters, 32 pound injectors, 52mm throttle body, Mac mid-length headers, 3.73 gears, stock LT4 clutch, electric water pump, comp cam dual roller timing chain, tune by ion. Any help would be appriciated.
