Check that the rings don't get pinched in the land, knock the sharp edge off of it with a detail file and run it. The valve relief cuts are sharper than that dent will be.
The bottom end in my car was in it when I bought it. Eagle/wiseco combo. At some point in time the exhaust valves contacted the Pistons. I spent a couple minutes making sure they weren't sharp, and checked the pin boss skirt area for cracks. They work fine at 40+ psi on e85, and have no knock issues running pump gas at 25 psi with a 35r sized turbo.
