I know that the engine builder gets all of the pushrods custom length for various applications. This was discussed at the time.

I will ask him to make sure he figured in the 1.8 ratio when determining length.

These rockers were used due to the 35 hp boost that they gave in a super ford mag test some months back. With a hydraulic flat cam these offer a good boost.

The question is do these rockers change the valvetrain dynamics (lift) to the point where the valve springs are not keeping up.
