Boss Valve springs

[93 lx]

I'm wanting to switch the stock valve springs for a set of Boss. I will be making in the area of 900rwhp, boost up to 20psi, and pulling up to 8k. Stock 14 heads. I'm asking if the Boss springs will be enough. Thanks

play it safe and get some good springs

Either
Trick Flow (PAC) 16801's 209lbs/in
https://www.summitracing.com/parts/tfs-16801-32 (1 kit Needed)
OR
PAC 1234x 230lbs/in
https://www.summitracing.com/parts/rsc-pac-1234x-16 (2 kits needed)

from what i remember, the 16801's are about the most you want to run full vct with, the 1234x's you should limit the cam timing... I could be mistaken though.
