I usually like to start by measuring the installed height of a couple of valves to give an idea of how much room I have to work with.

“Generally”, std LA heads with factory type valves can be tough to get much more than 1.700” height…….which limits the spring choices that will accommodate lifts over .500”

If you have 1.680” height available, something like a Howard’s 98412 should do the job.
