Header for 258

http://members.aol.com/_ht_a/imnotryan/Jeep/Image8.jpg

Thats a link to a picture of my engine bay, go for it!

My exhaust manifold is cracked and since Hedman header is virtually less expensive than a replacement manifold...... My only question is those bolts/washers that hold the I/E manifolds on... Once the exhaust is replaced by a header, and the washer holding the intake on will no longer brace itself on the exhaust manifold, will it bend or warp? i would imagine as your tightening it the washer will angle, and further tightening might bend the washer to the point where it cannot effectively hold the intake on before the bolt is even tightened all the way!

Also... seeing as it is these bolts/washers that held the exhaust manifold on before, what will hold the header on? the holes are all still occupied holding the intake on... I would assume Hedman or whomever would send with it a mounting kit or something to make sure you get it on, but in about 8 years i've never encountered such professionalism with aftermarket companies!

I just bought a DynoMax header for my 258. I am in the process of doing a full rebuild on a 1980 CJ7 and have everything a part. However, I have held my new headers up to the new long block and it is very apparent that these headers will be held on by the same washers that held on the exhaust and intake manifolds. They line up just like the exhaust mainfold did.

I hope this helps.

I had the same wrped exhaust manifold problem. I put on a 'pacesetter' hedder( cheapest I could find), and five months later no leaks. I used the stock washers, and have had no problems.
