Ben,
I have 2 manuals, one is the good old Haynes from Repco. Which we used to pull down the motor. And as Haynes says "fitment is the reverse of removal", I hope that is true..
The other one I got of eBay and it is titled "how to get more power out of an LS1" or something like that. Between the two books, they have had reference to just about everything we have looked at, or are trying to do so far. I'll let you know how it goes after this weekend, as we are rebuilding the engine this weekend.
Cheers
