Anybody have a good reccomendation? I bought a ProForm one from Summit and it doesn't really even touch the piston (even screwed all the way in). The motor is installed w/headers so I need one that can get in there.

Thanks fellas!

Get an old spark plug and knock out the center piece(it will take a little bit) and use threaded rod and a nut to put in the center...make it as long as u want.

I bought a " non fouler " adapter and threaded it for a 3/8-16 bolt .. works great
