I DON'T KOW IF IWANT TO GET A LT4 CAM KIT. http://www.hawksthirdgenparts.com/inc/sdetail/13341

OR JUST A SET OF ASM LT HEADERS ??

I'M OBVIOUSLY LOOKING FOR THE BEST POWER GAINS.
CONSIDER THAT THE CAR IT'S A DAILY DRIVER & HAS 170K MILES ON IT.
FAIRLY STOCK (K&N INTAKE & 80 SERIES FLOWMASTER)

any comments are welcome !!!

You can get that kit for 100.00 cheaper through Summit.

At 170,000 miles I'd save up for a rebuild. It surely can't be producing the same power as when you first got it. You can get a decent amount of power just by going with a crate motor or something. I know your in CA so emmisions will be an issue. So before I went to adding anything I'd seriously look at a rebuild in the near future. Better now while you have the $$ than to spend it on bolt-ons and then have the motor drop on you later.

PS, in no way am I trying to tell you that you have to do this. Its just a suggestion to consider.
