Just to say, you can use the same parts on a 'like' built engine, and you still have to measure for pushrods. Each engine can be enough different to require different length pushrods.

The mid-lift method for measuring geometry is the most accurate, or 'correct' way to determine proper geometry (pushrod length is the variable).

Contact pattern IMO is a poor way of measuring for geometry (pushrods).

Do it right, do it once.
