4sd911 I am at a loss to suggest another place to look for them. I have been here for awhile now and have never seen anything come up about this. Have spent way too much time on here over the last 7 years. (addicted)
I needed to redo my cam's and used the standard gaskets which I think were the graphite gaskets and they had iridescent sheen to them. Came from EBS but I have had then for 3 years before using them last fall.
