Here are the measurement and spec instructions, required for calculating correct geometry, that so many of you have requested.

1. Distance between the top of the rocker shaft and the top of the valve stem. Measure the distance between the combination square and the tip of the valve stem using a caliper, feeler gages, or other accurate measuring device. Be sure the square is resting on top of the rocker shaft and the blade is on the same angle as the valve stem. (See Photo)

2. Diameter of the rocker shaft and the roller tip of the rocker arm.

3. Rocker ratio being used.

4. Valve lift from cam card w/ 1.5 ratio rocker, or just lobe lift.

With these measurements and specs, you can contact me and I can let you know if correction is necessary, and supply you with the appropriate kit to make it perfect, guaranteed.

As always, I am happy to answer questions. I like questions.
