Interest in LS1 style long tube headers?

[FirstGen]

Thanks for the compliments. I do plan to make these for my truck reguardless however it will not be a priority unless I can justify a production run of the headers.
My PCM is located under my passenger seat and comes into the cab just behind the shifter in the floor toward the rear of the cab.
Yes I own a small shop in Rowlett. I can only take on one project at a time because most of the stuff I get is a full build up. I am currently building a pro-street/pro-touring '69 camaro with a forged LS1 and a custom PT-88 single turbo kit. We are going to keep heat and A/C in it also. Shooting for close to a 1000 horse at the wheels on pump gas and water injection. He wants it to be very tame on the street. No poor idle excellent drivability with insane power. It will be a difficult but rewarding project...
