cleaning up the slant six head

Not quite as defined or pronounced as it was yesterday but I though the picture would still be of interest. The part itself is down 6 inches under the sludge.

Im going to let it sit for one more day and pull it out. Not going to risk losing the intake.

The Vinegar does not touch the paint but the areas where there is no paint now to be seen were heavily corroded with rust. Very clean now, runners look good as well.
