Slide rail bearing bolts on a 190e 2.3 - HELP!

[srhorn]

I'm in the process of doing the head gasket on my son's 190e and I can't get the slide rail bearing bolts out! I've got the slide puller and bolts/washers and even removing the radiator and condensor to give them a good whack didn't make a difference! I've soaked them over night in wd-40 and warmed the head up and nothing. The whole engine is moving I'm hitting it so hard.

I've thought about drilling them out but I worry about getting shavings into the inards of the engine...

Any suggestions???
