Making headway, slow but sure.....

I just got the new headers for the '67. I bought Heddman headers for '65-'70 BBC full size cars. They fit PERFECTLY!!! They miss everything by 1/4" at least. I definitely recommend these to anyone doing a big block in one of these years. It was so nice to just bolt something on for once without having to spend hours cutting and welding.

Something a little different with these headers. They don't have collector gaskets. They have a swedge on the end of the header and on the reducer. Then use a clamp similar to a cat. converter set up. Pretty cool. It can flex and not leak. It's about time they came up with something different. The price was pretty darn good too. Less than Two bills delivered to my door.

Don't listen to me, what do I know? I've only been doing this for 30 years.

I had the same experience, see thread below:

Usually when you buy something cheap (especially headers), the extra labour required to install it is not worth the money you saved. I was impressed with the way my headers fit.

Yeah, I don't do Flowtech headers. I had a few sets where the collectors were pointing in two separate directions. One was pointing down to the ground and out toward the frame rail, and the other was hit hitting the floor pan and skewed in toward the trans. That was the worst set I had, but that's pretty bad. I've had great luck with Hooker and Heddman. I'm over joyed with the way these fit. I have Heddman's on the Nova and now the Impala. I've had Hooker's on some of my old Chevelles and trucks. They fit great too.

I even had a cheap set on one Chevelle, then was tired of constantly replacing flange and collector gaskets, so I bought a set of Hookers. I could NOT believe the difference. It ran NOTICEABLY better. Low end torque jumped up quite a bit with good headers. (I also stopped eating gaskets)

Don't listen to me, what do I know? I've only been doing this for 30 years.
