so cams are out obviously, three of the head bolts came right out, the other 7 aren't coming up as i turn them. my buddy says the threads are probably gone (caused by heat he said?) on the bolts or the block, whichever, but i need to get the head off. anyone have any suggestions? i've tried prying as much as i feel comfortable prying, but i don't want to damage the head. the block is done for anyway, spun bearing, and now probably head bolt threads, just need to get the head off. TIA.

 

anyone?
