Liberator diesels Oringed head

[6.0L_stroker]

Anybody use them or heard anything about them, also if I do get these what head gaskets should I use. i seen a lot of people talking about black onyx head gaskets, why? Also, what's the verdict on hypermax Oringed head gaskets.

[Evil Eye]

Use the stockers.

I've read that the o-ringed heads have caused dissimilar metal deterioration if you're using the fire crush rings.

If you're using the standard o-rings then you should be fine.

But I've never read anything good about the o-ringed heads on these engines.

I talked to EDE and Saint Joe Diesel about them, the conclusion I got was that they have never seen anything good out of Oringed heads in the long run, thu both said after 25-30k miles you will probabaly start to have noticeable wear on the mounting surfaces from the millions of harmonic vibrations

The oem gaskets and arp head studs will go a loooong way with HP. Black onyx is better if you want to get them.

most of the higer hp guys are not running orings on the 6.0. what are you planning to do with this truck? for the best possible results and the most longivity my advice is to deck the heads check for cracks and warpage. check the block for the same. replace the oil cooler and delete the egr cooler. add in some arps properly tqed and you will be good to go for a long time. the best gaskets, orings studs or any other part are only as good as the instillation. the arps are not going to stretch but if the surface is not flat the adhesives in the gasket will blow out
