Seems I'm with Bren, I was on last night getting ready to order the aussie gasket and found this post. Looks like I'll order the remflex instead. Anyone have info on being able to reuse the remflex ones?

i was planning to get the aussie units a while back. then i heard a tale of how they failed. it was under extreme conditions. possibly any gasket would have failed in the same conditions.
the remflex are domestic gaskets. they come from WA. u can find a local dealer or order online.

i've never seen a gasket that dealt with exhaust gas that is reusable. if the aussie's have that going for them, u may want to go that way.


i like the remflex. it even survived me!


D~~~!

guess I'll be doing the port relief sooner than later, just ordered the remflex. I'm just sick of replacing the gasket and/or waiting for it to leak

They remflex gasket looks a little lacking in that theres not much material at the edges. What do your think.

The aussie gasket sure looks like it would be less likely to push out just from looking at it. I know theres more to it than that, but arn't both made from Graphite?

From my years of using graphite gaskets in industrial applications you might be able to use these puppies again.If they don't peel and flake much when removed and you don't clean the left overs on the head and flange areas they should seal again.That being said,these are THICK and I don't think they will have any sealing problems first time around.Looks like first time and done,won't be any leaks.The package says "If you don't like 'em You haven't tried 'em".Gasket looks goood,fact if it had T.#t's I'd ask it out for drinks

Brennen,These remflex are beefy all the way.Not positive but believe the oz gaskets are maybe metal? with a layer of graphite on both sides.Remflex is a thin fiberglass core with mucho graphite on both sides.

When I replaced the Aussie gasket it delaminated down to the metal core. This occured between the third and fourth intake ports. It just stuck to the head and manifold too good. The bad part that blew out was only on the number 6 exhaust. The last stud on the head leaked water and disintigrated the graphite down to the metal core and blew out.
The Aussie gaskets have layers of graphite layed up over a metal core. If you change headers every week maybe you could spray teflon on them to keep them from sticking. That might work........

The Remflex have allot of thickness, much thicker than the Aussie gaskets.
They are pure graphite, (not layed up) and there is no metal core so you can't bend them. I have been told that they may separate on removal but clean up very well. I have not experienced this yet. When I make the switch in a few months to a Weiand 4 barrel I will let you know. For the price I will have another set ready to go when I do the switch. They seal so well I could have torqued them at 5 inch pounds.

They look real nice once torqued, sort of a puter/chrome shine. On Brennan's motor they would look good. Mine is that clean but painted blue. If you need pictures of the install send me an email.

after a short run to the muffler shop, with open headers, i got a great new exhaust system. when i could hear again, i noticed a leak in the Remflex area of #4 exhaust. the area i was worried about, #6 exhaust, sealed up real nice. i tried retorquing the nuts, but it still leaked. a washer between the Clifford flange and the triangle piecs closed it up fast.

i really like these Remflex gaskets!

D~~~!

Has anyone measured/compared to see if the Remflex gasket has smaller port holes than the Aussie gaskets? The Aussie gaskets seem way too big for a stock application.

I'd like to have Aussie gaskets with Felpro sized holes in it...

Danny

Yes, I have a picture of them over-layed. I tried to capture the difference which I thought was very significant. I am not sure why they ported them so large. From what I have heard and seen the SL6 head can not be ported that big with out hitting the water jacket.
It would be nice if the Aussie gasket was the same as a FelPro.
The RemFlex and FelPro are identical in size. The RemFlex are about the thickness of (4) FelPro.

If you want to see the difference send me you email and I will send a 3MB quality picture.

Danny,

With the RemFlex you don't need to torque it very much or as hard as spec. I torqued lighter than spec so it didn't crush at all. They seal super well and with the lighter torque it allows the manifolds to move around easier.

I gasket matched my head intake side only to the FelPro. I was afraid to open up the exhaust that much. I went about half way to the FelPro. Maybe some one can verify if it is ok to open the exhaust that much?

I am curious if anybody has successfully opened up their SL6 head to match the Aussie gasket. It is sure is big! Maybe it is dual purpose and used on the Aussie Hemi.

Danny,

I installed the exhaust manifold first and lined up and tightened it enough to stay in place. I also enlarged the holes since it fit way to tight over the studs.
Doctor Dodge said to get it up as high as I could and center it so it can expand and contract with out hitting the studs.

Then I installed the intake and tightened the center nut to align it. Then I put the stove bolts through. The center on has lots of wiggle room to align. The outer ones may need to be drilled to allow it to line up with the offset your referring to. I drilled mine, used stainless bolts and washers and nuts. The ports lined up better than they were in stock form.

If you need a picture send me your email. It's very clear, 3MB file.
