So after fighting with my engine build and bender trail quads i could not get rid of low end puke so i put reg pipes on and it came out of it its 8bu with decked .30 cyl and .63 base shim added ports on intake and mains opened up about a 1/4 in my question is should i have opened the piston boost port and did some timing adv to make this work i know its not alot of info but 8bu weights emty seemed to work but still no hole shot engagment at 46 ish
