Do you need shorter plug for header clearance? If so you may want to run a regular length plug and buy or make a special spark plug socket. This may be a blanket statement but I have never had a set of bosche plugs that were worth a darn.

I asked mr.gasket and they said....

The FR3LS crosses over to a 0416 or 0416S shorty plug. They are a 14mm and a gasketed seat not tapered. Thank you.

FYI:http://www.splitfire.com/links/links_cm.htm

these plugs definately work, I must have run 800 laps on a short track testing them.

Also as far as header plug access. Try going to a auto parts store and digging through their cheapo tool pile. I've cut up wrenches, and cut sockets down in a lathe and welded others to make it easier to change plugs.
