Anyone know what the NGK equivalent to Champion RC12YC is? Edelbrock recommend RC12YC's for their heads but think I'd prefer to stick with NGK.

I tried the cross-reference facility on NGK's site but it must have come up with 20+ different plugs!!

Thanks for that....maybe the BCPR5ES then to match heat ranges...though I won't really know what heat range will suit best until this engine is up and running and I can experiment a bit.
