Just took the second head off the 98 Subaru Outback I'm working on and I found one of the alignment dowels was badly crimped over the gasket for about 1/3 of its circumference. I have no idea how it got that way, but unless I do something about it, it's going to be very hard to get the new gasket on it without damaging it, and even if I do it's probably not going to seal right.
What's the best way to deal with this? Is there a decent way to remove and replace the dowel (even a damaged one like this)? Can I just dremel off the crimped part (taking care to shield the block)?
Edit: Here's a photo showing the good one (on the upper left) and the crimped one (on the upper right):
