Since you mention cleaning the block deck w/o anything protecting the cylinders, I'd like to make a suggestion from someone with quite a few (non- LC) HG replacements under my belt.
When you've cleaned the block, use a shop vac to get most of the debris out of the cykinders. A small piece of tubing duct taped around the smallest nozzle does a better job. I use a clean shop rag with carb cleaner sprayed on it to wipe out each cylinder when I'm done, too.
Also, after you have the head on and before you put the valve cover back on, pull your drain plug and pour a quart of cheap motor oil over the whole top of the head and let it all drain.
This will clean any dust or crap that you've accidentally gotten on the cams and valves before it works its way into the bearings.
