valve noise

[sneaky11]

Just start a newly rebuilt motor today, its a 416 12.5:1 with hotcam stage 3... the valve noise make me a little bit nervous, so if some guys here can tell me if it's normal or not after watching this little movie...

I notice while putting the piston in, that the pin is loose in the piston hole... is that normal? can this be the knocking sound? Did the piston will expend and the pin get tighter in the hole?

thank guys!

[edit]: here's an aother vid... we can hear it better!! I think!

Check the valve clearance. Just sounds like the lash is off to me.

Found the problem... Wrong wrist pin in the kit... too small diameter... I need info on this picture... Does My piston is still good to go? I hope so... damn why I don't check it... :mad:
