1967 Camaro 327 L30 4 Speed Adding Headers

Hey Guys, my 67 convertible is a stock original car (a driver), including the factory dual transverse exhaust. I have a 327 L30 with 462 double hump heads, 4-speed car console shift, tilt wheel, power steering, and power brakes up front. I was thinking about installing headers with a new exhaust. I would like to install a plug and play with everything fitting with little or no modifications. Your thoughts and recommendations. Thx Tom

I would value the originality of the stock exhausted more than the headers. I have never seen headers fit well around the steering box on a 67.

Roger, I would like to wake her up and add some sound and hp. The car is very quiet stock. Like you, I am torn with taking out the stock exhaust. Decisions decisions.

If it was me, I would change out the exhaust and keep the manifolds. With the headers it's not only the steering box, but clutch linkage, melting spark plug boots and speedo cable, plus the alternator mounting. I had no choice with mine, I bought the car with headers, I am considering changing mine back to stock manifolds. I doubt you would notice any performance gains, moving to headers.

I just finished installing the summit racing full length ceramic headers on my '68 327 4 speed. It was more of a pain in the butt installing them than I thought it would be. Not because of fitament issues but because lots of little unforseen issues. If your alternator mounts on your original manifolds you'll need to buy a new mounting bracket. I bought some spark plug boot high temp covers. Replaced my steering rag joint while at it. You'll need to get new exhaust pipe bended welded up at the collector to fit. I think I need to re-tune my car since she breaths better. My car sounds better, looks better under the hood, feels a tad stronger, im happy with it all. But I like wrench on my car when I can so the work didn't distract me from going the header route. Summit did a great job with fitament. No banging dents in pipes for clearance or anything. Really depends on what you want.

I used Doug’s on my original set up. Fit nice but I do have manual Steering. Passenger side goes in from top and drivers fro bottom. Do have to remove Z bar.

Hey Guys, After reading everyone's feedback and giving it some serious thought. No headers. Taking off the stock exhaust, putting it away and installing new aftermarket stuff. Thanks for all your input.
