ok guys i bought mike's (10secsomeday) former 1.95's and SDD is putting them in saturday...my question is what is your opinion on springs they offer me both 90lb and 105lb springs.....im probably going 105's but i think they may be comp cams springs and not crow cams.....but i dont wanna go 90lb because i dont feel like fukkin with my timing chain....whats your thoughts on this?
