I've finally got some money to spend on my 01 5.3L Tahoe but I keep going back and forth on what to do w/ it. I want to get as much horsepower w/ say $3000-$5000 as I can w/o going to forced induction. I have been think about going w/ stage II heads, 1.8 rockers and a set of headers. I would like to get as many suggestions and/or testimonials as possible before making a decision. Current mods are K & N 77 series, hypertech flash (which I am definately getting rid of as soon as I decide on other mods) and a flowmaster cat back system.

Thanks
