Default Re: What mod should I get.

Hang in there JOBA you are in the right place for answers. Sanding the head professionally known as lapping the head. Find a pane of glass 12x12 or whatever and spray down the back side of a sheet of 400 wet/dry sand paper with spray glue. With cylinder head in hand, using circular motion the goal is to sand down the squish band so it is even and shiny. I usually count 100 motions, then twist the head grabbing each quarter of the 4 sided head (400 motions) altogether. I use Marvels mystery oil as a lubricant on the sandpaper surface and with each interval I mop up the sand paper with paper towel and apply a fresh dousing of marvels. This works well for me. Others may respond with diff techniques that are equally effective.
