Not sure if they are still available. Crane went belly up and shut their doors a month or two ago. I have a set, love 'em, and if you can find them. DO NOT use the crazy instructions they give you for setting pre-load on the lifters. Treat it like any other small block adjustable rocker and they install easily after that.

spendy but worth every penny
YAY reference lol. Ya these cars are not the best car for modding....i am really hoping to break 330hp with the headers. I have a cam and intake so that should add to the gains. But i have been disappointed with every other mod with the exception of the intake so who knows. I am getting them installed in a few weeks, along with new brakes and MAYBE functional brake ducts. As soon as they are installed my car will be on the dyno so we should know quickly what these cars can really do.
I want to go ahead and thank everyone for making this all possible. It took more than buick and william to get it done. It took the entire forum and we really came together on this one!!! great job!!!!

I really want to put them on but I am waiting for some other parts to arrive first. I only want to do it once and since the cradle will be down it should be a piece of cake. I will probably be going to the track in July or August after the engine and trans are completely finished and somewhat broken in. I hope to break into the 12's with no nitrous or turbo...

I worked on mine today and almost have the old manifolds/crossover/dp off. Just the rear left and I need to remove the belt, alternator, and rear valve cover since I have the tall valve covers 
The front and crossover came off well, but the dp is still bolted to the Magnaflow res section.

I was feeling like a 10mm bolt holding it in place, but didn't figure out the right angle to get it yet. Once that's gone I was thinking of bending it a bit out of the way. Damn the GM bastards who designed this!
Dam.. Bad news fellows. I don't think we will be able to install a different intake without moving the crossover pipe. I was looking at my stock intake and I have about an 1/8" clearance between my intake elbow and crossover. Our stock intake inlet has a slight angle pointing the tb upwards and the LS1/LS6 intakes neck is pointing straight. This will crash the tb into the pipe! I'll find out in a few weeks I guess but now my belly is turning!
Truck tb is too big so a adapter might move the tb out just enough but I'm worried.
