What spark plugs for stroker engine?

[GASnBRASS]

For anyone running a stroker, what spark plug are you running?

Turns out the champion RC12YC that Edelbrock recommends for their aluminum head is a typo, the electrode reach is too short. Motor is nearly a point higher compression so I might need a colder plug. I'm running the old school distributor ignition so copper or platinum doesn't matter.

What did you wind up settling on for plugs?
I just got my 4.6l in my tj and it pings a bit when i lug it with the stock rc12lyc plugs.

Have you asked Golen what they suggest running for spark plugs on a stroker?
