I looked at the Jeg's web page and they have numerous shorty style hedders. Has anyone installed these on their cars? I will have to weld air tubes to make it legal in SoCal. I want to know if it will be worth the money and effort to go this route. I have to keep the car smog-legal and I feel this is the only way to go. I have also considered the LT1 style exhuast manifolds, but I was told that my stock exhuast y-pipe is a different configuration and won't bold directly to the newer manifold. The exhaust flange exits further to the rear compared to the stock 78 style. The Jeg's page is www.jegs.com. Any input will be appreciated.
