Aluminum 225 Headgasket

Search on www.slantsix.org. There is a group (or other site) dedicated to the aluminum blocks. At one time they paid for a group manufacturing run. Will be costly, so pull the head first and see if yours is even salvageable. I read that often the parts are so corroded that you can't resurface by milling, but don't let that scare you. Cool if you get it fixed. I would love one of those engines.
