Hey guys, I am about to order GM Stage 2 and the Pulleyboys 2.8" pulley. I have a couple questions... will I need colder plugs? If so, which ones? Also, the 2.8" is easy to swap with the GM stage 2 one, right? Thanks!!!

yup. that chart sums it up pretty well... is it completely accurate tho?

 

that looks to be describing the intense kits...i will be going GMPP. Will the same rules still apply?

 

but what plugs should i be running with a GM stage 2????
and what should i be running if i go GM stage 2 + 2.8" pulley?
