Finally got the head back for the '79 300SD and going to install it this weekend. Any thoughts to offer this rookie as to the "proper" way to prep the work area? Specifically have stuff on the block surface that would come off really well with a green scrubby or a wire brush and some Marvel Mystery Oil. Want to get it "hospital clean" before laying the new head gasket down. Also, there appears to be some hardened material on the upper cylinder ring sleeves that would be great to clean up also.

Thanks!
