Dont waste your money trying to make power NA.

you would be better off just buying a VTEC head and putting it on. Youll make more power with a VTEC head than you will with all that crap you just listed.

If you are serious about going turbo, then most LS people need 404s and springs/retainers. Milling the head is the opposite of what you want to do, dont do it. Porting is a good idea, but it depends who does it.

Personally i would jut buy one of the $300-350 VTEC heads on here, a skunk2 intake manifold, GE LSVTEC kit and swap it out. THen i would get it tuned and keep the revs below 8000 so your block doesnt let go.
