Hemi header gaskets ?

My headers are kinda getting warped at the flange and i am looking for a thicker gasket to help seal ? I am using copper ones now and they leak a little any body knaow of someone who make a better gasket ?

 

I don't use gaskets !
I just use permatex red high temp silicone

 

Header Gaskets

Not sure what type of heads or flanges you have but I have good results using Felpro #1418 which is a fiber over metal core gasket and fits my AJ Stage 2 fuel heads.. no leaks. Reusable and works for me.

 

High temp silicon works great normally.
Flanges getting wrapped? how thick are they? have you weld the pipes togheter properly ? if not the exahust pulses will make them "dance" and wrap the flanges.
This is after adding some extra bands on them.

I use SCE gaskets cooper gaskets they are thicker and havent had any problems I also coat them in cooper gasket spray. call Caleb hunter at SCE and tell him Jonathan Pickett told you to call. Caleb is great to deal with.

 

Call Clark...they make a real nice reuseable thick header gasket

is that video after adding some bands? what did it look like before?

 

Yes that was after the first reinforcment, dont have any clip on the first runs but we had to change flanges after 3 rounds since they were wrapped. after that video we also put in small plates between the outer ends so now they are solid as rock.

We made oure header tubes from thin walled stainless tubing and the flanges are thin for light weight.
