unfortuantly outside of Texas...
I have a set of cams for my twin turbo setup

.556 / .576 max lift

what valve springs should I run? it seems all the .600 lift valve springs I find are for two and three valve motors, and won’t allegedly fit a dohc motor.

I’ve heard rumors GT500 valve springs might work if I have the seats machines. so I’m looking for some guidance

What is the exact specs on your cams? Are you saying they are over .550" lift? I would HIGHLY HIGHLY suggest you do not run these cams if that is in fact true, you will have nothing but problems and it's going to cost you a lot of money fixing broken parts all the time. My cams are .480 lift and it makes 1350whp. The valvetrain is really happy too. Trust me on this now...don't do it. I would highly suggest you get with Todd Warren aka NA_SVT for a cam that will actually work.
