Ls1 Engine Build Head Bolt Hole Cleaner

Conveniently enough, ARP sells a tool specifically for cleaning head bolt hole threads on LS1 engines (discussed in the tools article elsewhere in this issue). The tool works just like a tap and can be turned with either a 1/4 open end or a tap turning tool from a tap and die set. Treat it just like a tap: turn it in slowly, and back it off every few turns to help loosen the goop on the threads and prevent jamming the tool.
