Default Spark plugs?

Not really sure if this is the right section but I was curious if changing my spark plugs would be good or just un-nessisary. My H/C is in sig, heads are milled to 59cc and Im running approximatly 11.1 CR.
So would it be a good thing to do? Why and what type of plug would be best?
Thanks all.

Grab a set of NGK TR6s and gap them about .038

.38 is the measurment of the gap between the spark plug electrode and the "prong" at the top of the spark plug... different setups require different gap sizes

most people keep theirs gapped around .50-.60.... mines gapped at .55 i believe...

General rule of thumb is when you add 100+ hp over stock, step down a heat range in plugs, i.e. TR6s
