Look for a UD pulley in classifieds. I bought one for $100 shipped

Cams and Heads at the same time is usually the proper route to take.

You mentioned you already had an LS6 intake, but you could make a decent amount more with another intake. That's really the only thing I see that's left other than sticky tires.

Underdrive pulley. You can find a good deal on a used one if you look.

Keep the ls6 intake...if I were you I would do heads/cam/springs and if you have extra money do the ud pulley...
I would buy some 350-400 dollar 243/799 heads before spending 200-250 on a pulley no doubt...
The only thing is all the extra stuff with a head cam swap (gaskets, bolts, etc)
If you keep an eye out for good used parts you can do it for cheap, just be careful when looking at condition of used parts, I did a 243 heads, comp 224/230 cam, 918 springs swap with new oil pump and chain for under a grand...Good luck man
