This route isn’t cheap but it’s a winning formula.

Thanks for the advice. I may end up doing valve springs and retainers at some give some insurance when running higher RPM's, Katech oil pump is also on my mind. I may forgo the E for now and see if I like the power I get when tuned. I'm prepared to do a low side pump at this time, but not low/high/injectors.

Sounds like a good plan. The big advantage to doing the injectors and HPFP now is that the blower has to to come off to replace them, then it’s only about an hour job to replace both items. I did mine while I waited for Kong to do their magic.

Should I stay with stock heat range plugs, or down a step colder?

If you cross over the 600 WHP threshold then you step up to heat range 7 plugs. If not, you stay stock.
