Kooks would like to let everyone know about our new 2" race header for the ls1 Fbody cars. It is made of 304S/S. It features equal length primarys. Weld on collectors with our velocity spike for the increase of exhaust scavaging. These headers are also avaliable with the LS7 d port flanges for the l92 and the LS7 heads.Here is a link to our new product page of our website showing and telling you all about them.http://www.kookscustomheaders.com/show.php?pid=840

PART #'S ARE 6501-2R 2 X 3 1/2

6501-2R7 2 X 3 1/2 WITH D PORT FLANGES

 

Nothing but the best from Kooks!

 

cool now I need to build a 460+ cubic inch motor

 

Wonder how a 454 would like these?

D.J.

 

Wonder how a k-member would like these...

 

awesome george, now i don't have to have the local chassis builder build them for me. another great product once again buy kooks. let me know what the part # is for the lS7 style flange headers.

 

That kind of motor that needs that sort of header often has already had a motor plate installed. Say good bye to Motor mounts

 

I am sure they will fit fine with an aftermarket k member, probably with a stock one, but I can't imagine anyone that would need these that would still have a stock k member on their car. I'm sure the motor mounts won't be in the way.


Thanks Kooks, I will be buying a set of these in the spring.

 

well ****...Looks like i need to sell my stepped headers then..

 

Looks great George!

Any chance of getting them stepped .... 2" to 2 1/8" ?

I know Steve had asked you about the strait 2" and the stepped, dont know if you have gotten back in touch with him yet.

Did you see the Pump Gas Drag article yet? Has a Kooks plug in Steve's write up.

 

Any dyno num#'s from kook 1 7/8 to kook 2 on a stroker motor. I am very intrested.

 

Looks like I will be buying a set of these for my LSX Block/C5R head motor.

 

Like mine.

whats up george. looks like you got them going!

 

I run them .they were worth a good bit over my straight 1 7/8 both were also kooks

 

steve give me a call so I can take care of them for you.

 

What about 2 inch stepped to 2-1/8th with 4 inch slip fit collector?????

 

how big of a difference do these make compared the the 1 7/8's? will there be a big difference on the street or are they mainly for strip only?

 

anyone?

 

Dam, right when i ordered my 1 7/8 stepped to 2!!!!!

 

I am on vacation but ill try to call today.
