I'll agree with the above! unless taking FULL advantage of the additional flow, not worth it..
I've owned a dozen cars/trucks with headers, two in the driveway now
![Roll Eyes (Sarcastic)](http://67-72chevytrucks.com/vboard/images/smilies/rolleyes.gif)
and they can be a royal PITA
noise, leaks, heat, leaks, underhood space consumption, leaks, collateral component heat damage, leaks, etc..
good luck!
