Yes another "what size header do you think" thread.

Since i damaged the headers when I crashed I need to buy a new set. The last pair was a set of Hedman with a 1 3/4 primary and a 3" collector http://www.jegs.com/i/Hedman/500/68190/10002/-1 and was wondering if I should move up to a set of Hooker Comp with a 2" primary and 3 1/2 collector http://www.jegs.com/i/Hooker/520/2457-1/10002/-1. The car has ran a best of 10.46 @ 129.7 with the old.

Heres a little about the car:

468 w/ 12.5 to 1 pistons, Square port Iron heads (mild port and polish) with 2.19 in and 1.88 ex and 118 cc combustion chambers and H/S 1.7 roller rockers, Team G intake, 850 Holley w/ a Blue FP, Comp Cams flat tappet w/ a 580 in and 605 ex lift, Headman 1 3/4 primary and 3" collectors , T400 3500 stall, 12 bolt 4.10's w/ spool, ladder bars and coil overs.
Car weighs in at around 2700 me in it

I will be switching to a PG trans in the near future

Thanks for the info

maybe consider stepping up to some 2 1/8" headers so that way you can step up that cam and heads in the future? but for now I'd go with the 2" headers.

If your car is a "RACE CAR"

invest in a adjustable header.
IMO!:rolleyes:

Super Comp Adjustable Racing Header
Part #: 2304HKR
Hooker Adjustable race Headers allow you to change your header primary tube lengths, collector lengths and diameters and collector types (Classic 4 into 1, Merged and Split–Flow). By altering the relationship between the primary length and collector diameter and length it is possible to increase or decrease the torque and horsepower output at any specific R.P.M. level. For a slick track the header primaries or Collectors can be shortened to decrease the low end torque for better traction. Larger diameter Collectors will also reduce low end torque. On a good track with lots of bite, extending the primaries or Collectors will pick up bottom end power for a harder launch and awesome e.t.'s. Smaller collector diameters will also increase low end torque. Hooker adjustable Headers have taken more Pro Stock drivers to the championship
than any other brand.

I'd upgrade to 2".

I run these with my 502. (Hooker Super competition)I'm sure your 468 would work very well with your setup also.
