Default 85 tpi 3+4....

Hello folks I haven't done anything major to the l89 because I'll be getting a c5 or sti in November.........but I feel as if I have push the c4 as far as she will go.....keep in mind this car was not running when I got it......now I'm just about done doing basic things to bring it back to life from it's 15 year nap I took.....I want to gain 50 to 60 hp with out doing a complete swap or boar I'm looking to spend around 600 maybe ..........I was wanting to do a lt1 intake...cam... different heads...and long tube headers......

****what would I need to do to fit a lt1 intake on a l89??

****What heads should I go for....or should I just do rockers and springs???

Short of a nos kit am I missing something else I can do to gain some hp???
