Whats the difference between short and long headers? Is it power noise or just obviously the fit.

 

Long tubes will produce more of a gain .

 

Long tubes will provide more of a power gain while shortys will not... shortys are more for emission compliant individuals.

You'll be able to find more information in the external section and the "search" function located at the top of the homepage.

 

shorties a better for low end torque and small cams supposedly. I have long tubes on my LS1, shorties on my LT1. I'd go with longtubes just because its so much easier to replace spark plugs haha.
