To maintain proper rocker assembly geometry it is imperative that the distance from the camshaft to the top surface of the cylinder head be kept as near as possible to original. You'll note that if the block or cylinder head have been surfaced the pushrods now effectively rise further even in the "down" position. This does not give you more lift, in fact in severe cases it will reduce lift, and in any case it will increase wear and noise. The easy and only solution to this dilemma is to raise the rocker assembly by shimming the rocker pedestals. These shims are .051" thick and can be stacked to the height necessary. Sold individually. Also fits the Sprite , MG Midget and Morris Minor.

When you are trying to build a motor to get the ultimate of performance you often optimize the life expectancy of the entire assembly. One such area centers around the rocker assembly.
