Debating on plug heat range.
K, I'm starting with an '07 Ram, doing a ported eagle head swap with the thicker head gaskets, so compression ratio should be in the 11.0 range. I will also be running a Zex kit through an 85mm Nitrous Outlet plate and building up to a 125-150hp shot for track days. I'm pretty set on the nitrous side of things, I'm just wondering what plugs I should be running, whether I should be running 1 step colder or 2 steps colder. I will be running 91 octane at best and will have a nitrous tune, but I keep flip-flopping over my plug choice given the slightly higher compression ratio from the head swap.
Basically I just need to know if I'll be fine with the 1 step, or if I'm just safer with the 2 step colder.
