What would you do,???.

Tnx for the new pix. IMHO, there is the discussion of stock pistons and rings, vs KB's. If you use the KB pistons, the top of the top ring will be right about .285-290", or a bit more than 9/32", below the deck, and will hit any ridge in the bores. So let that be your guide if you continue with the KB plans. It looks like the ring will travel over that one pit down near the existing ridge. Whether or not the KB rings will reach that large group of deep pits further up, you'd want to measure for .285" or about 9/32".
