Hello all! Owner of #446 back here again with some more questions.

So I've taken apart the engine originally to check the state of the head gasket and cylinder head, but both seem to be in fine condition..

Then I noticed some pretty deep lateral marks in the wall of cylinder 3. Also, did the original block come sleeved, because it seems like mine is?

I was just wondering if I could get some feedback from the community as to what my next steps should be?

The block is currently still sitting in the car but I'd be willing to take it out and go the whole 9 yards with it if I had to.

Thanks!
