oh, the domes that stone sent in with the motor are the same ones he got back, but re-cut (rough as fuck as i said). now when you cut a stock stroke dome and make it into a stroker dome, you of course cut the step of the dome deeper and the chamber deeper (to keep it simple). now what happens when you make those cuts and screw a spark plug in?... the spark plugs hangs into the dome chamber 3-4 threads worth. Now ive cut domes like this for myself, before have the cnc available to make blanks and domes however they need be, and you must run copper washers under the plugs so when screwed in they sit flush with the chamber. stone was charged $75 for new domes, not to re cut the same domes and fuck them up in the process.
