around 10rwkw difference. If you can pick one up cheap enough they're easy enough to swap

Might just add that seeing you have a HSV and it's a VXII.... It should have the LS6 manifold already.

You can check by looking at the middle of the manifold on the passenger side and look at the serial number.

LS1 S/N# 12560688. & 12556333.

LS6 S/N# 12573572. & 88894339 - 12561184 & 12561182

The fins on the bottom will need grinding down to clear the early-LS1 coolant pipe setup (vents to all 4 corners of the heads). Or you can replace with the later setup that only vents the front corners, but hard to buy them locally. Seems to be worth 5-10 rwkw depending on other mods, stockish motor will be at the lower end. Worthwhile if you can pick one up cheap (seen em go for $50ish on ebay).
