Ls1 Engine Build Thread Cleaning

Look at all the crud that comes out of each head bolt hole! Between holes, clean the tool with Brakleen and then shoot it with WD-40 for lube before you hit the next hole. You can probably just ask your machine shop to do this thread cleaning process for you if you don't mind paying a bit extra (there are 10 M11 holes to clean per head and it takes a little time).
