If this is accurate, I can see cams that resemble FI (your others listed) valvetrain actions causing you to potentially lose a good bit of power if you remain NA and try to make big numbers off motor and/or spray
AND terrible if you ever decide to go FI. Those cams being FI based won't save you from your .4 CR increase. You will be sadly disappointed on your curves and power. Just my 2 cents.
Furthermore, this clarifies why BTR Stage 4 is legitimate gains and why I laugh when I see "cam only" quote 490ish rwhp. I have E/Ts .3-.5 faster on 1/4 on cars with same mods boasting cam only and 485-490hp.
You can scroll down to the very bottom of the page to get you a quick answer.
