I have 2 more gaskets going out, after these two, we will either start selling them if there is no problems, are get a few more out if there is any problems, but so far everything is working good. I got about 700 miles on mine so far, with no problems.

 

Looks like your gasket is graphite almost what is the wire size? and is it .060?

 

Id have go back and look thru emails and such, but the gasket is the same thickness as the stock gasket and the rings are .010 thicker then the gasket. Not sure what they gasket is made out of. But I will find out.

 

thanks I am knocking out touch base tomorrow

 

intrested in these gaskets keep me updated

 

well not a very good update, went out tonight and was really getting on it, doing a lot of wot runs, and blew the gasket, there was a full steady stream of air going into the overflow tank and I had coolant blown all over the place. So I will try round 2 with it, but this time I am going to do things alittle different. I think the gasket will hold fine running studs with it, but only running 120 ft-lbs on these bolts was not near enough, so I will have a new set of them coming, but this time Ill go right to 140-150 ft-lbs with them, instead of the 110 i went with at first, also trying to do a hot retorque on them I think I just stretched them all and ruined them. This is the first time I really pushed the truck hard since the retorque, and I think I might have made it worse. The way this gasket is designed, i can pull it out, clean up the coppper coat on it, and put in a set of new rings and try it again. I am going to try it one more time with this gasket and these head bolts, if it fails me again, then I will drop in 425's. I could throw them in right now and probably be ok, but I want to do some testing and see if my original plan will be good enough to hold. I have learned a few things not to do again, and that is the point of this gasket and setup is trial and error. I head back to work tomorrow for two weeks, so soon as I get home, I will be pulling the head, cleaning up the gasket and installing new rings and bolts, and torquing it down tight enough from the get go, this time.

 

If you have a pic of the blown area please send to me or post its the weak link area and needs to be addressed also a hard mounted dial indicator with a locking second needle would tell how much the head was lifting in that area witch it was mounted a remote elc dial sencer would show you lift inside the truck like a snap on scanner kinda . Also what bolts are you using? Aircraft grade next?

 

On a stock gasket the weak link is in the fire ring, mainly inbetween the cylinders where it is the thinnest, the rings seperate and the spot welds come apart, and the rings in the layers break, so I am betting this gasket failed in the same spot, because it was not tight enough, I wont be able to tear it down for two more weeks though.

 

any recent news on the gasket

 

ill be home tomorrow night from work and will tear it down in next couple days
