Thanks for all the Replies guys. I really appreciate the help.
Fla54Chevy3100,
Thank you for your post That helped me decide on the split header. For right now I will be running the stock intake and exhaust manifold with a smithy's glasspack. The exhaust is all rusted so I have to replace it anyway. But when I do buy the Dual Intake I will be sure to buy the split headers too right away.
Now I know why I love this website. Thanks again Josh
