Header Education

I'm in the middle of a ground-up restoration on a 67 Coupe/289. Will be putting an Edelbrock carb/intake/cam package in the engine and will be porting, balancing & blueprinting.



My knowledge of auto mechanics is old school. The last set of headers I purchased were Mickey Thompson Avengers in about 1970. Obviously, the technology has evolved so that are now long tube, short tube and Tri-Y headers.



What's the difference between these styles and are there advantages to one over the other? In other words....why would I want to use "shorty" headers instead of long tube?



Thanks in advance to the list

Well Im know expert but one reason to choose shorty over long tube is shortys are a heck of a lot easier to install. There is also equal length shortys and unequal. The equal makes more power than the unequal but usualy interfear with the sparkplugs / wires.

Equals only make slightly more power in the midrange. Unequals make slightly more power down low and at the top end. Not really a dimes worth of difference overall.
