LS1 Cylinder Head Bolt Thread Cleaning Tool
At the factory, GM uses a substantial amount of thread compound on the LS1's cylinder head bolts. This is good because the head bolts stay put while the engine is running, but it becomes an issue when trying to rebuild one of these engines. The leftover residue clogs the threads in the block and won't allow new cylinder head bolts or studs to install properly.

Enter ARP's PN 912-0011 LS1 Clean Out Tap. This tap is the correct size and length to properly clean all 20 of the M11 cylinder head bolt holes used on the LS1 engine, allowing head bolts to reach the proper torque and head studs to thread in easily. Price: $51.34.

Re: Thread cleaning tool ?

Thread chaser sets aren't that expensive (Craftsman, for example) and they become one of your most-used tools in working with old cars.
