180 degree headers

My newest project has room for a set on a small block chevy. They look cool. Is there a performance advantage?

yes

Yes there is an advantage. They do change the sound of the engine as well (I have a set on my Camaro). One thing, they do radiate ALOT of heat even with header wrap on them. I would recommend a ceramic coating and heat shielding on adjacent items you don't want cooked.

They improve scavenging, thus improve engine breathing and making more power. They are also hell to fabricate, but look amazing when done correctly.

I wish you luck.

Speedway sell a set for 239

I have these on my car, the second ones, part 180-2 http://www.schoenfeldheaders.com/180_crossover.htm

They are cheap enough that I didn't even want to try and build them. Speedway has Schoenfeld as well as their own brand.

180 headers will change where you have power and/or torque. More power and torque? I'd love to see the dyno comparison!

They are quite popular with the Pantera crowd, and required on GT40s.

In reply to DavidinDurango:

OK, so a quickie google search cleared some things up for me. A well designed set of 180 degree headers Should give you more power throughout the rpm range. Instead of designing for more power up high or low like a typical set of V8 headers you Should be able to get most of the both high and low rpm peaks. So I guess I should say "yes, more power under the curve"

Where is Wheels777 when we need him??
