Quick question before I purchase..
Budget build for my '95 mustang. stock 6.0L/S480/ Speed inc Tu2 cam… will these springs suffice? They are rated to .600 and the tu2 is in the .580's.. not sure if throwing boost at this is going to make the 1218's a no go. What say you LS1tech?

Seat pressure is what's important with boost. If you don't have enough the valve can hang open. We have seen this problem with a 76mm starting around 15 psi. It would make 800 or so until that point, after that it would go down hill and show it was rich

A lot of the stuff that can hit peak boost/torque early is going to have some backpressure.
On the intake side you are of course starting the compression cycle at IVC.
On the exhaust side you may see double the pressure you see at the intake and at EVC you'll get valve bounce. (and it noses over hard).
I wouldn't personally set up any turbo LS with 130 on the seat but that's just my opinion
