Those look like remnants of a drilling process. Probably been there since manufactured. Are they aluminum or ferrous?
Definitely magnetic, not aluminum. Wire wound steel, something that would have been a part of an oil seal. I suspect that when the rear main seal was pried out that the spring remained in the case and was mangled by the rotating crank shaft!
Wow! Hard to believe that whoever removed that seal didn't realize that there was supposed to be a spring in it (they obviously came away with only a piece of plastic/rubber on their pick). Maybe the spring fell into the case/onto the shaft, prior to removing the seal? That would most likely cause the seal to leak... Maybe the seal was pushed in to far upon initial install? Lots of questions, and I suspect many more to come. Good luck with the tear-down and subsequent build
Today went well. I was able to borrow the cam holding tools from a fellow PCA club member and rennlist poster and was able to remove the camshafts, lifter towers and cylinder heads. I found what I think is the source of my intermix problem.
Hard to believe that a small crack can cause such a big headache!

A hairline crack in one of the heads?
I had to say, something. Marked...
Please add photos and more details, if you can. We love threads like this.

This picture is from the number three cylinder.The crack can be felt when dragging my finger nail across it. Based on other posts I was expecting to find it on cylinder number six.
Congrats! Check with Len Hoffman. He should be able to fix this and make sure you send BOTH heads (in case there are other cracks) because you don't want to do it twice.

Thats the easy one to fix as per Len Hoffman($450) that goes from spark plug hole to welch plug. The hard one ($750) goes from spark plug hole to exhaust valve guide..

Good advice and that's my plan. I'll ship them out as quickly as I can, possibly as soon as tomorrow..
