HEaders or rockers. Cam, etc. Anything that causes more valvetrain noise then stock.

rockers mostly.. more clattering sound. You can always wrap teh stock modulein teflon tape.. it is like putting ear muffs on it, essentially what a LT4 would do, but a lot cheaper.

No, no reprogramming. What headers are you going with finally? Did the dyno sheets come in handy?

Yes they were handy even though I couldnt really tell how the curves differed. I am still not sure on headers. If I cant get a good deal then its JetHots.
