ZL-1 big chevy headers?

[dahkahuna]

I'm now in the market to buy headers for my A/SA ZL-1, all input will be appreciated. Now convince me with facts on what type header you'all think is the best for this combo. I have talked to Jere Stahl,Jack Davis, Mark at Perfprmance welding, Dawsons Headers,ETC. Most everybody tells you what they will sell you and the price with no info as to why they think it's the way to go ,except Stahl he said he has tried and tested,( his customers have dyno'ed and gave him the results) most fadd combo's 1 step, 2 steps, stainless non-stainless,tri-y's,merge or not ? ? ? straight up hookers coated cost 1100.00 to as high as 3000.00 is this really neccessary ? Over the years I have tried many differint header combo's pipe size seems to be the most important factor all the other is just romance bull, but I am open for some proof that spending 3000.00 is cost effective for the performance gain inplied. thanks Doug
