Default Has anyone had clearance issue when using .563 intake and .568 exhaust for a cam

Has anyone run a .563 intake and .568 exhuast for a cam on a stock bottom. I was looking to hear if there has been any piston clearance issues with using this cam?

Thanks in advance,
Jason

That would all depend on your heads. If they have been cut down a lot or if they have overly large valves. But on the norm you should not be anyway near having clearance issues.

The heads were milled .002"
And the valves are 2.02 intake and 1.57 exhuast.
