The engine seems to run great. But when I get on it it kinda lags off. But I have noticed the ford ticking sound starting. I tightened all my header bolts and it quieted down a bit but it is still noticable when I get on it. What could that be? The front of my motor has oil leaking on it but not much. Should i try to re-seal my intake. And what is the best way to tighten my rocker arm nuts.
