D15B ENGINE STARTS NORMALLY, BUT WHEN RPM REACHES 3000 , THERE IS A TAC TAC SOUND NEAR THE FIRST AND 2ND CYLINDER VALVE

1987 Honda Civic

D15B engine had a timing belt broken, already replaced camshaft, timing belt camshaft pulley, engine ok running normally at idle.

Have you done a cylinder leak down or a compression test to see how the engine is sealing up?

Were the valve clearances adjusted? You need to readjust them after some running-in as the camshafts was replaced.
