Gasket's???????

"NO CLASS"
Exhaust:
Ok are the SCE copper exhaust manifold to head gaskets the best to get? Do they have a turbo mount gasket and if so do I need it?


Head gaskets:
Which are the best for a High boost build since I have been told Fel-Pro's (or Fast Blows as one fellow put it) are no good? I know there have been some problems and several debates but it hasn't come up for a while and the "search" was old info. Anything new or at least tried and proven?

Thanks!

Re: Gasket's???????

If both you mating surfaces are flat on the turbo & exhaust manifolds are flat,, you should not need any gaskets.
Head gaskets,,,,, ask Mike Ghettosled here.

Nothing wrong with Felpro gaskets as long a s you retorque them. Cometics are the ultimate high boost gasket (other than an oring setup)

Re: Gasket's???????

what do you mean by retorque them? torque em up to form them, then back it off and redo it so it seals?

I may need them.

torque the heads to proper spec (usually 70 ft.lbs w/studs) and heat cycle the engine 2 or 3 times. (heat up cool down.........x3) then when the engine has cooled down to ambient air temp, go over the bolts/studs with your torque wrench one more time (we usually go up 5 ft.lbs on the settiing as well.)

There is other ways (back them off and retorque) but we have found this makes no difference.

Hope this explains it.

What "head to exhaust manifold" gasket do I use? I have the victor’s from RPM, but a buddy told that they will blow-out and to use high temp silicone in there place. Has anyone had this problem?

DO NOT USE A GASKET!! Use high temp silicone and nothing else.

turbo engines + header/exhaust gaskets = BAD LEAKS! :tdown:

Are you going to do it with the engine in the truck? I just wonder if it would be easier to pull the engine first and then redo it, if you have the time, space, and tools.
