made me curious also, typically what Ive seen is rust or some other long term direct wear, no sign of anything else in or on the head, and surely the PO didn't put it in there on purpose. it has pained me to spend all of the money I have now gone through to get this car back driving but with surprises like that I am hopeful I will get more than planned, especially since this killed my short term hopes of having one of Blueprints engines.
