Put it on a piece of wood, this will allow you to fully penetrate your head (dirty thoughts, ) Since you are only going one MM larger you should be just fine as far as alignment goes. Oh be super careful to keep metal shavings out of your camshafts and valves, ect. Better yet would be to dissassemble the head and do it. I know that in some cases I have used a healthy dab of grease to keep metal shavings at bay congrats on getting ## head off bty!
Yes, you could use a glob of grease to catch the shavings. As far as which end to start at, I personally would start from the top and go through the bottom. Then get a countersink to use on each hole in the bottom to ensure you don't create any high spots.
Have you check to see if the old bolts fit in the head just fine? Because it does sound like you got the ol' switcharoo
I would reccomend that when drilling the head bolt holes to use a drill press, to ensure that your newly drilled holes are perpendicular to the head surface. If they end up at too much of an angle you may still have problems fitting the head.
Since we're talking goofy, I ran into this problem once. The head had been overheated/boosted so much that the bolt/stud holes oblonged from the stress. Take a close look to see if those holes are actually round.
