SB/RA donor
Hi. I've removed the head from my donor engine and found that two of the head bolts were rusted along their full length and were an absolute B****** to remove. A couple of the others were oiled up and the remainder were uniform grey and looked almost unused. I haven't done many full rebuilds and none at all for several years and haven't come across this before...would a headgasket failure be enough to cause this? I haven't removed the gasket from the block yet but couldn't see any obvious sign that it had gone. Any ideas?
