Default Diamond Pontiac 4.350 Pistons

I have 7 diamond 4.350 bore pistons,the skirts have been coated as well as lateral gas ports and lightened inside also, these are in very good shape yet, a couple have some dings on the top from foreign material hitting them and all have marks where the exhaust valve was touching them.I would’ve reused them with new rings unfortunately I had to go just slightly larger on my bore. I’ve already called diamond and u can get the replacement piston for $265 that was a couple of years ago, to duplicate these it’s $1400+!These are perfect for a budget build or even more
