Innovative's O-ring heads

Anybody used these? I'm going to be doing headgaskets soon and I want to just replace my heads. These are cheaper than stock and offered by a company that me and thousands of others trust. What do you guys think?

Not sure about theirs, but I'm running a set of 0-ringed heads from liberator performance

Superstroked, you like them? Good quality? How long you been running them? They come with proof that they are flat right? I know even some of the brand new Ford heads come warped.

i'm interested in hearing about this too. when i bought new heads (reman stock) i thought about fire rings and ported ect. but from the techs I talked to was that if they are installed perfectly they work awesome but there is such little wiggle room to get it right and for my application ARP's new heads and stock gaskets were more than enough. and the tech felt more comfortable installing them. (this was done at a performance shop).
i would imagine though that if innovative is putting them out they are top notch.

oringed heads are not a good idea inmo on a daily driver truck. they do not last as long as regualr head gaskets. the guys making the most hp are not oringed in the 6.0 category, and there is a reason for that

If you did decide to go with o-ring remember even with ARP studs you will have to re torque the heads after initial start up or they will leak. that was a question i asked Eric at innovative diesel stock or black onyx gaskets do dot need to be re torqued

These are half the equation in my opinion.

In our high compression drag race engines we O-Ringed the block (cut a groove into the block and install a wire into the groove), used a malable gasket (copper is the norm) and machine a matching "reciever" groove into the head. When torqued down, the ring mashes into the gasket and into the reciever groove in the head, making a total seal around each piston bore. This works exceptionally well in high compression, supercharged or turbo engines!

With just a o-ring and a gasket you sill have the block surface "flat" and compression can still get past the flat surface. Not worth it in my opinion!

I thought that the o-ring heads were grooved too? It would be pointless to have an o-ring between 2 perfectly flat surfaces.
