Stock headers or shorty???
Anyway, I'm also building a similar car an LS1. I could probably make long tubes fit. But I'd like to do side pipes like the Caterham, so I'm thinking about shorties.
I'v seen pictures of the holley. It seems to fit well. But the tubes are small, and the flanges are kind of low and angle inward. I think more designed for a swap into an early chassis.
Then I came across this picture of a set of BBK's. Bigger tubing, horizontal flange, and the flange is maybe a little bit higher that the holley. Obviously, these are on backwards to fit a specific chassis.
I think I'm going to be using these shorties for my car. but I have to get the engine into the chassis first and see how it fits.

Thanks .boB for the reply and great pics 
You're right, those are nice looking headers.
I had kind of resigned myself to getting a pair of Block huggers (I haven't ruled them out) but somebody only 1/2 hour from where I live has a set of stock headers going cheap, they've been bead blasted too so look like new. The stock outlet is just under2 1/2" inches he's told me.
I do not know whether the just under 2 1/2" outlet would cause any big restriction to the power output compared to block huggers.
What size exhaust system pipe does the LS1 have from header, is it the same 2 1/2" inch measurement?

I've heard only good things about the SS OBX headers like these http://www.ssaccessories.com/servlet...-Header/Detail
Might be worth a look.

I really want to put Cobra type side pipes, but I'm not sure that they'll fit. If they won't fit, Then I'll use long tube headers.
