You can run 1.6 or 1.7 rockers with a cam, I've run both....just pick a grind that will work.

When I did my rebuild, I used the following pusrods. Are they good, or would I need to upgrade again?

Melling Pushrods
MEL-MPR-462
These Melling OEM replacement pushrods are perfect for stock rebuild or mild performance applications where open spring pressures do not exceed 300 lbs. They are manufactured from steel tubing and work well with stock or aftermarket rocker arms.

Best to stick with 1.6 stockers with an aftermarket cam unless you feel your grind is not aggressive enough. Moving to 1.6 roller rockers will eliminate some valve train friction but probly won't notice anything.

Your pushrods are not compatible with guideplates, you need hardened pushrods. The ones you have will quickly wear down from guideplate contact if you install stud mount rockers.
