Thanks all.

The heads all use turbo plugs. There was no need to do standard plugs with having these made up.

You are correct in basically just glow one plug and start the engine and the other plug will glow up but for those that wanna make sure that the plug is glowing, just simply touch that plug with your igniter and go. There is a sound difference from using the standard head button and then the dual buttons which want more fuel once it is running.
