Stud mounted rockers are a budget decision, and there are no clearance issues with any of the three length's I came up with.

1. pattern centered on lash cap- .657 valve lift, rocker short of 90 degrees to stem, and the largest sweep width. 7.975 pushrod length.

2. used plastic Moroso rocker ratio tool. .662 valve lift Pattern slightly towards exhaust side of cap, but much narrower than #1. rocker still slightly short of 90 degrees to stem. 8.060 pushrod length.

3. Rocker 90 degrees to stem [half lift method] .660 valve lift. Smallest sweep, but pattern still slightly towards exhaust side of lash cap. 8.100 pushrod length.
