1.5" or 1.52" Roller Rockers
Im using stock L98 heads (ported) and I want to use either 1.5 or 1.52 ratio roller rockers. Im not using the 1.6 because the head requires some modification. So out of 1.5 or 1.52 wich will work best??

No significant difference.... a little over 1% more valve lift, is all.... so, something like .517", instead of .510", is all you'll get. I doubt you'd be able to tell the difference even on a dyno.

Ok thanks, now I have some clarity to this. So I guess I'll just go with the 1.52's the comp ones are I believe the same price. So what the hell, it can only help.

they not only give you a little more lift they also open the valve a little faster
making the cam have a little more duration in the upper lift erea of the lobes. not to step on eny ones toes but you will see more power.
