compression or flow?
Others will know better but I believe with ported W2s you’re going to want high lift. Around .575 to .600 at least that’s what I’ve always thought. I know with my combo my compression isn’t that high. So looking to limit duration so I don’t bleed too much psi but have higher lift than I presently have. Definitely a solid flat cam. Since you have kinda unknown factors I’d get to measuring and calculating what you actually have
