I want to run some Rocket Autolite spark plugs, but it appears rocket has retired himself from HT... does anyone know where to find rocket, or if there is a chance rocket will be back on HT?

And if I can't find rocket, here's my spark plug question (i searched and read what there was to read). I'm hearing that stock NGK coppers work fine on a stock b16 (mild bolt ons) but would it hinder my performace to run platinum plugs (NGK) with 9mm wires (vision wires) that are made to run with platinum plugs? Any info would be great. Thanks in advance.
