Head bolts jamming in the block and won't pull out.

Hi guys, hoping for some advice here and an easy answer but getting worried.

I started the job of changing my head gasket and have run into a problem getting the head off. Eight of the head bolts came out nice and easy but two are jammed and won't pull through the block. They were a little tighter than the others after the initial release but now they are just spinning (but are still quite tight) at the point where they should just pull out so looks like they're jammed in the block. I tried prizing them out with a screwdriver while unscrewing them but they just got tighter and tighter so I screwed them back in again to the point where they should be free but they're still tight and the head still won't come off.

I think there must be bits of head gasket or swarf from knackered threads on the bolts which is now embedded in the shafts of the block.

I'm thinking I might have to pull off the sump and oil rail and either grind off the threads so I can pull them up or grind off the heads so I can pull them down. Does this sound feasible but if I do will I then be able to get the new bolts through?

In a bit of a panic now so if you have had this before or can give any help would be very grateful.



Cheers

Ali
