Installing Flowtech headers Tonight, it begins 
i should be able to write up on it a little saturday or something. Look back here for how it went i'll edit this post.
*************EDIT**************
Ok they're installed. it wasnt that bad really. I had to take out the steering rod to get the driverside header in and drop the starter with the passanger header. Other then that it was basically straight forward. everything went fine and they look great. I want to get the car dynoed on the 6th but i dont know if thats going to happen because tom at speed inc said they werent planning on dynoing any cars. the y-pipe went up really easy to the headers too, that itself probably took 10 minutes. For what i paid im rather happy

Ok here's my review on the headers quality blah blah. For the price that they cost im happy with them. There is a little texture to the pipes and they're kind of scuffed up. I'm not really worried about that though. the y-pipe is flattened in some areas which i figured it would be when i bought it. I'll take some pictures of the flattened areas tonight before i put it on. I'm going to be posting pics of thea headers and the y-pipe and after they're bolted up etc. these are the first actual ls1 headers i've seen but im sure they dont compare to the hookers or a $600+ set of headers but that's expected. the only thing that im worried about is blowing gaskets since they're not slip fitted headers. I'll find out and just hope i get the bolts tight enough where they wont blow gaskets.
Short version - they are basically a lower quality hooker, i was told they have the same bends and the same design, its just that hooker is slip fitted.

I personally won't buy them now after seeing the primaries dented like that. If I wanted a 1 5/8 header I'd buy one. Nope I gotta have un-dented primaries. Guess I'll keep shopping, Just my .02, Fred
, fitment is not exact so if it was for k-member clearance what about the guys that dont need knotching, there stuck with a dent primary?

In my experience Hooker quailty = however the Hooker design is excellent.

Uhhh... everywhere I've looked online they say Flowtech = Holley, not Hooker.

1. you dont HAVE to grind the block for a header install but its better than having to take out the steering shaft as this take about 1 minute with a sawsal
2. look at your stock kmember when you get a chance youll notice its already been cut and welded at the spot where your having to cut again...next everyone will be on GM's case for this

i bought the headers unaware of the dent, but it has been taken care of and thats why i went ahead and installed them anyways. My y is uncoated because i have a feeling there's going to be some cutting and welding to it so i didnt get it coated. i planned on having a cut-out installed so there wouldnt be a point. The headers have been good so far. i reused the stock steel gaskets also. the ones that came with the headers looked liek garbage and i wouldnt use them.
