you are gonna leave a ton of power on the table with block huggers.... the bends are way way way to tight. You'll be chasing your tail trying to get that thing tuned properly, and all tht motor potential is gonna be waisted with those things... not that sanderson makes a bad product, its just that block hugger headers are about as bad as you can get (performance wise).
for the money you have tied up in that motor, spend the extra cash on the stahls.... Jere can make them to clear the AC and his new ones are designed for the raised port exhaust. The only headers I know of in that class.
yes they are expensive, but when you figure in how much better they fit, and how much better your car will breathe... you'll be glad you spent the cash.
plus they are tuned equal length, not shorty block huggers.
