hey guys, doing a 1.6mm over bore 13.5 C/R making a 1043cc k8 GSXR 1000. keeping stock K8 cams with APE adjustable sprockets. not looking for anyone to tell me to go with different cams right now. looking to bump the top end power a bit. i mostly ride the streets but i do obey the speed limits so im not looking for a street race bike lol i do take it to the 1/4 mile alot and am shooting for better trap speeds. what cam timing do you guys suggest for better top end power with OEM cams but with 13.5 compression and 1.6mm overbore? i have heard of 105/105 and i think 110/106 alot. wanting more top end POWERR lol, anyone have any dyno graphs of their OEM cams degreed?

oh and even though stock cams i am doing stiffer valve springs, are OEM retainers still fine?
