Plug a smog hole

The 360 is on a stand,heads on the bench.

There you go...........It won't get any easier than right now. Just take your time, a little cutting fluid, though no really needed, the graphite in the iron acts as a lubricant, it (cutting fluid) falls under the realm of "it doesn't hurt". "Tap Magic" is an excellent product. If in your search for a tap and "T" handle, if you have a choice 2, 3, or 4 fluted taps (4 is most common) buy a 2 or a 3, they are a little stronger than a 4. If a 4 is all that is available, that's ok also, it will feel a little more "springy" as you turn it.

Good luck.
