Header question! Hey guys! I am having a H/C/I 383 LT1/LT4 built. Its gotten no (reasonable) expense spared. 
Question! The motor is supposed to be about 550/600 HP. I have been looking online at G-body long tube headers for my LT1/4. They sell many size headers... what would be the best for my application?
1 5/8 primary? 1 3/4 primary? or a custom pair of 2" primary?
Assuming 2" primary to be the best, would the additional cost of a 1 3/4" to 2" for an additional 3 or $400 be worth it? Would there be noticable gains?

What peak HP gains can I expect? Is it worth the additional 3 or $400 for used or $1000 for custom made 2" primaries? Or should I just buy some hooker 1 3/4 and be done with it?
What kind of realistic gain would I see? If I had 2 cars... built exactly the same with the only difference being the header and we raced... would I gain a half car or more from 0 to 120? or would it be barely a bumper?

I would go with the kooks stepped 1 7/8 headers. Probably the best performance per $ in a case like this (over a custom setup).
As for the G-body call them and ask if they make them or can make them.

Headers One Day Down The Road U Will Have To Prolly Go With 1 7/8 So I Would Get Them If U Find Them I Think The 2 Inchers Mite Be A Lil Overkill Especially For The Money!! Its Like Buying Injectors Now U May Need 36 But Later U Know U Will Need Bigger So I Just Always Go With The Ones I Think I Will Need In The Future Saves Having To Try To Sell The S*** And Loosing Money!...my Opinion
