    just port & polish the stock one, you wont feel much with the bbk 80mm, the stock unit is 75mm. Port it, save some money for more worthwhile mods

    if you got stock bottom end stick w/ stock TB. a cleanly ported stocker will support bout anything you can put behind it w/ stock cubes.

    you'd be better off findin an ls6 manifold if ya havn't already done it already.

    ls6+ fully modded stock TB will gain your probably upwards of 20-25hp to the wheels.

    A well-ported stocker will be close to 80mm.
