These are hedman hustler headers for a small block chevy. They are specifically designed to fit into the stock thirdgen engine bay. Here are specs:
- 1 7/8" primaries
- spreadport exhaust bolt pattern
- every bend in the header is mandrel
- they have 3.5" collectors

Some things to note to make them work in your car, you must have:

- a ministarter
- you must relocate your oil filter
- your heads have to have a spreadport exhaust pattern or you have to buy adapters from Jegs and they'll work

Other than the above mentioned, they'll fit with no problem and me and Craze Inc saw them in a firebird and they did fit nice

These headers go for about $800 BRAND NEW

Thease headers ARE BRAND NEW. You can tell because the tubes haven't discolored except where the welds are.

I'm asking $400. Would prefer to sell locally, but will ship

let me know
