Anyone running the lunati 703 voodoo cam?

I questioned why I needed dual springs for that cam. Seems like they would beat the seats up into the head after a while. I have a 4 speed with 3.23 gear but might change the gear to 3.55 or so being that I like to launch from stop signs etc. I will have to talk to my machinist about that. I am running a racer brown ssh-44 in my other motor and love that cam. I know it wouldn't work the brakes tho, hence the lunati. This is the reason that I posted the thread and all the info is really appreciated. Thanks for your reply!

More valve seats have been killed from too little spring load than too much. When the valve hits the seat it needs to hit it once. If the spring load isn’t enough for the mass of the valve train and the valve hits the seat and bounces it will pound the valve job right out of right quick.

I had a cam grinder tell me several years back if it was possible to get a spring with 340 pounds on the seat and 340 over the nose that’s all he’d use. That of course is impossible but his point was seat pressure won’t kill a flat tappet cam. The over the nose load will, but not seat load.
