So, how do I do it? I am having the head milled, but what about the block? clean it with a razor? I'm just not sure. I have looked in the MHG thread, and thier is no mention of it. BTW I DIDN'T blow my HG before i took it off.
If it isn't then take out the 2 pieces of doul that are on each end of the block. Take a razor and go over the block for quite a bit trying to get all the crap off. Then lap the block using a drywall sander and the different grits of paper. I can't remember which grits but I'll check that today for you.
Yeah....I used some solvent (paint thinner I think) and a razor blade and didnt have any problems. Is damn hard to scratch the iron block with a little razor so scoring shouldnt be an issue. Just make sure that where the MHG seals that you cant feel any bumps or ridges with your fingernail.
