I am looking to put headers on my 85 CJ w/ 258 and am wondering which ones you all would recommend or have experience with. I am leaning towards Hedman because of price and have heard good things in the past. I know the Borla would be nice to have with the stainless steel but for the price I can get the Hedman and the rest of the exhaust done. Thanks in advance for any suggestions.
I used Clifford Performance Headers on my last 258 "Built" motor, but had one complaint. they were two piece, and were joined where you slip one of the tubes into the other. I forever always had that very slight exhaust leak, and it used to pi** me off, because I hear every tiny noise, and a noise like that is irritating on a performance engine.
So, just watch for where the joint is in any you are looking at, maybe Clifford changed theirs, i'm not sure.
I've used Clifford headers(and an intake)for the past 7 or 8 years on my CJ, two piece, dual outlet. They've got some pros and cons. There was definately a difference in how the enging runs, more power but how much is attributed to the headers alone Im not sure. Its a little tight under the body with 2 mufflers and pipes and the collector gaskets do blow out every year or so but they're cheap. Installation is easy and they'll last.
Hey, there's a trick to the collector gaskets! I had a custom exhaust system made at a local custom exhaust shop (after I put the headers on), and he used Aluminum gaskets, all they were simply were about 3/16" solid aluminum plates, and were the same shape as the collectors with the right holes.
If you check with a local exhaust shop (not MIDAS, LOL ), they may have them, or make them for you. All you do is put the orange high-temp exhaust sealant on them and bolt them together, and they last for years, I never had one blow out in the 8 years I drove that CJ.
I have hedman htc. (High tec coating) headers they're pretty nice. I also used copper header and collector gaskets from mr gasket, and used the double thick lockwashers that came with the headers.seems to work well no leaks! and they dont loosen up.
