custom heders?

very few of the headers you can buy are true equal lenght so i dont think that would hurt you to much on a mild engine, dont know about prices and such in US but you may find it easier and cheaper to buy some cheap bigblock headers for a E or B body that you can use the flanges and colectors from and you also get alot of usefull bends ;) just a small idea´that may save you some money and work but i may bee wrong
