yeah, 220 is the max i'd recommend on a non-vtec sohc...200 or less if you really want it to last. mine just past 4.5 years in faithful service and passed the 130k mile mark.

give me a call...i'll get you a basemap to drive it up to us. you can either come to the shop to get it or i can meet you between the shop and/or in gwinnett area.

sounds like you're on the right track regarding the setup.
