Well Keith, I think your partly right. There are gaskets that will make up the difference in height. But if you mill and deck I don't think this will help. And besides, I would think that this would defeat the purpose of decking and milling unless you just had a clean up and were going with a stock rebuild. Any other ideas out there?
