Do I need roller rockers for my build?

Kirby,
I don't understand all that ratio stuff and how it effects the actual lift on the valve end. I won't have any issues with the valve/piston clearance. I won't have issues with the valve/valve clearance either. I've checked that. I know that my motor is breathing very well already from the last build at 1.625 ratio. Am I really going to gain all that much going to 1.7?
PS...my brother is sending me some stock rockers with 9000 miles on them on Friday. I'm going to inspect them and compare them to my 30,000 mile rockers.
I'm still considering the rollers though.

Very true, but, I believe that those units from the Moco do have good merit, in the hands of those that can set them up correctly, and can add to lower lift grinds as a means of producing more, without the purchase of new cams. Just sayin'.
