Headers for 67 El Camino with 350

Any suggestions for headers for my 67?
It has a 350 in there, and i believe it was originally a big block car.


-Good fit, no denting and bending

-Able to change plus with them installed
-Good seal
-Would be nice if it had an O2 bung


anything else I'm not thinking of?

Re: Headers for 67 El Camino with 350

67 ElCamino owner, I went with Sanderson cast headers, very good fit and best of all, NO LEAKS! I don't even use a flange gasket. 02 sensor placement varies, a 4 wire self heating sensor should be down stream a bit, narrow band sensors are used closer to the collector. Plug changes are a NON issue. I will never go back to tube headers on a street car, the Sanderson units are good for 500 hp and ground clearance is great. Run 2.5" pipes w/H cross over and turbo style mufflers, my 327 with a 150 N2O shot ran 12's

Geoff, do you have a link or a part #? Most of the sandersons i am seeing are tube headers.
Block hugger, shorty, full length?

Any pictures of them installed? I'm still running slightly cleaned up original 1967 cast iron manifolds on my ZZ4. I don't know how much torque I'm leaving on the table, but I like how it sounds, and runs, plus I like how they literally will last forever.

You found them! Sound wise, the ticking/clicking sound of tube headers is gone, depending on exhaust choice, should be no droning. They fit great and I had NO clearance issues and NO leaks. Can't post pictures, son has my car till July.

I installed a set of Hedman 68298 on my '67 with 383. Fit very nicely; had to jack up drivers side a little, even on a lift. They cleared my clutch "Z" bar, and only two areas needed "modification"., but NO denting or banging. No O2 bung, but that's easy.

On drivers side, lower control arm, rear bushing,; had to grind about 1/4" inch from lower housing to get it right...slight grind, not a big deal.

Also, #5 plug clearance is tight; I used short plugs, Autolite #104; ground a little off plug top/tip so boot would clear header, about 1/4" again, and have no problems.

Passenger side fits, clears, no problem...drivers side had both issues, but not big deal. They don;t hang low but they are not even length: passenger side collector extends about 3-6" further back than drivers.

Check Amazon for deals..
