who hear has put headers on their cars, i was thinking about this cheap upgrade... do they help any? i was gonna get a holly system.

Yep lots-a power if you just put on straight headers. :D

I have headers.
Make the car LOUD.
Good HP gains as well.

ok 1 more question-- are headers universal, or do you have to have certain sizes for certain engines?

Headers are NOT universal.
Eash engine is different, and therefore, needs its own set of headers.

good ol' Hooker Super Comps!
