Maybe grasping at straws during the winter boredom....
I run a 402 BBC in stock. I use a 1 7/8 to 2 inch primary. I'm sure you are not that far off with a 2 inch Hooker. Most of the guys that run BBC high HP cars in stock use a 2 to 2 1/8. I would be surprised if you could pick up a tenth with a header change. For the kind of money you would spend on a good set of headers you could find more ET with something else. BP
