Pulled the heads. All holes appear to be steel based on the cross hatching in the cylinders. All holes are 20 over. Pistons are all Promarine based on the part numbers. Block is a clean freshwater block based on the water passages. The heads were also decked based on the hatching on them as well. Will need head gaskets unless I can track down a replacement set.
