Valve lash 0.006 IN, 0.007 EX, Plug are recommended. Ngk's gapped at .052, Timing, I set the engine at tdc, lined up the cam gears and slapped the dizzy on (I know noobish), I know that will make it rough but if you go to my profile and click the gsr running issue thread there's a video of it running to give you an idea, I tried twisting the dizzy to see if it changed and it did but not a lot, I also popped the plugs off one by one and that also seems to change it BUT I unplugged the map sensor and nothing changed so I'm suspicious about that.
