Urgent: Need Advice On 454 BBC Headers For 71 Nova

Not to sound contrary to what's already been discussed, but a 2" header is a bit large for a relatively mild street BBC. A 1 3/4" header will easily support well over 500 HP, usually with the added benefits of more low end torque, plus they almost always fit better and offer better spark plug access than the larger tubes do. I haven't priced any lately, but they used to be considerably more affordable than the larger tubes as well.

Just something to think about. I fully agree with Eric!
