Looking for a couple recommendations on spark plugs for a mild race build. Just to get break-in and dyno done without issue.

Flat Top Pistons .004 in the hole
0.040" MLS Head Gasket
Performer RPM Heads - Ported
Approx .615" Lift Solid Lifter Cam
Trick Flow Single Plane Intake
Firecore Distributor & Wires
Hooker Fenderwell Headers
MSD Ignition
4-5,000 stall w/727 & 4.30 Gearing

NgkBRK6E is what I would run. Use the same plug in my 10.5:1 strokers.

 

[PRHeads]

RPM heads use “C” series plugs.

NGK BCP6ES or BCPR6ES

Looks like the BRK6E is basically the same thing.

NGK 5s. The 'K' has the ISO nose, which I believe projects slightly further out into the chamber. Using these in a 4 heat range & very noticeably improved idle quality.

Thanks Guys. Will try out a set of those BRK6E's. Look pretty reasonably priced as well.
