This has been a debate among friends for two days now. Will someone who knows please help settle it?!?

Here's the debate:

When installing a set of valve springs, there are a number of factors to be considered. And they all relate to each other. Among them are minimum and maximum spring height and seat pressure.

Accepted assumptions:
1. seat pressures vary slightly from spring to spring
2. install heights vary slightly from head to head

Debate:
Should the installer adjust each head/spring for consistent/optimum spring height thereby accepting a variance in seat pressure from valve to valve?

or

Should the installer adjust each head/spring for consistant/optimum seat pressure thereby accepting a variance in spring height from valve to valve?

Thanks!
