The motor is a 1999 5.3. Its going to have a turbo setup on it. I bought new lifters already and found a deal on the PAC 1205X valve springs. Will these work with a factory LS1 Or LS6 cam? also would it be a good idea to do a trunion upgrade to the rockers?

Thanks!

Yes those will work, however most people would recommend a dual valvespring for forced induction.

From my research I thought they were dual valve springs?

Oh my bad, I thought those were their beehives. Then they should work just fine for your application.

And yes, a trunion upgrade is cheap insurance and a good idea to replace the crappy needle bearings that come stock.
