Would the 1.6 make somewhat of a diff, meaning is it worth the money?
What stud size would I need if I were to consider this?
Going from 1.5 to 1.6 rockers will give you some extra power. It's like putting in a slightly bigger cam without all the work. Going with a roller tip vs full roller depends what you're planning on doing with the car. Your factory studs should be 3/8.
The roller tip rockers will fit under your valve covers and are good for mild applications. I ran a set for 70k miles & they were still in great shape.
The full roller rockers are for more high performance use and have more clearance issues (valve covers, springs, pushrod length).
