I used VHT paint and followed the instructions to a "T", oven cured the parts a per instructions on the can,then wrapped the parts individually and set them aside for thirty days.Preparation work:cleaning,cleaning,cleaning some more...then sand blasting (while avoiding mating surfaces)...then...cleaning,cleaning,cleaning....then put the parts in the oven before painting to offgas and get the remaining petroleum based residue off of any parts,clean some more.
If you do sandblast, know that the sand WILL clog oil passages, ruin any ball or needle bearings on the way, but I found it was the easiest way to get the surfaces roughed-up and reach in those hard to get to spots like between the fins on the cylinders/head.
Pretty happy with the results, as it did not scratch whilst moving the engine around during ssembly,it is not bullet proof but touch-ups are easy and quick cause you always keep a can handy.
