Re: How to set valve spring load?
you need to measure installed height with a gauge and measure spring pressure with a special tool. its easier to take them to a good machine shop that does performance work and has all the proper tools.

Re: How to set valve spring load?
Seat pressure is only one part of having the valve springs set up properly. If the cam lift is too great, the springs can bind or the bottom the the retainers can contact the top of the valve guide/seal. Unless you have the special tools, having the heads set up by a machine shop is the best way to do it.
