Valve springs for howards cams

Beware of coil bind with any single springs with that much lift on LA heads. Usually you only have 1.62-1.65" installed height, which makes .500" lift and up really tough. 1.65"seat-.500"lift-.060" safety margin=1.09" bind minimum height. So you'd have less, like 1.07" theoretical.
