Ls1 Engine Build Bolt Hole

Now that we've checked everything out in terms of measurements on the block, it's time to start our final block cleaning. Begin by inspecting all threads in the block, both in terms of bolt holes as well as holes for oil gallery plugs. Look for leftover sealant as well as any damaged threads. We discover that our head bolt hole threads are pretty gummed up from the thread compound GM used when originally assembling our LS1. This could interfere later on with proper installation of our ARP head studs, and could also prevent proper torquing of head bolts (if used in lieu of studs).
