98 Z28 A4. CAI, Pacesetter LT's, Pacesetter ORY, Borla Catback. 3.73 gears

The car has 138,000 miles on it and I want to put cam and converter in it. I got a good deal on TR230 brand new so I wanna go that route. Right now I just want to put cam and other stuff you guys recommend to do also (lifters/valve springs/whatever).

Future mods are LS6 intake or Fast 90/90 combo and I won't get new heads but get mine ported. Will this work and will my motor hold up? What springs and lifters and pushrods should I get.

Thanks guys
