Black Onyx or stock head gaskets

[blackshadow]

OK So I spoke with a person, from a sponsor on PSO, and he told me that his opinion was that the stock head gaskets were better than the Black Onyx!!! I'm going to use ARP studs. Almost all the threads I've read here state Black Onyx are the ones to go with. Help!!!

I got my onyx from Adam at FCDP and they were very nice gaskets and a little cheaper than stock. Not sure why fords would be "better" thou.

It's debatable. IMHO you'll be fine with either and a good set of studs. As long as the heads and block deck are true before you bolt it back up you'll be fine. Also make sure the heads aren't cracked. Do all of that and you'll be golden no matter what gasket you use.

multi layered steel gaskets are good all the way around,hell they use em in race application...fords gaskets are good,but the black onxy are coated in a rubber substance,which in the event of a scratch or som other "MINOR" imperfection,will fill it in,given the tremendous force the arp's are gonna give ya....thats the only thing i can figure the diff is...other than that,there both good,i would go with the black onxy,ive installed hundreds of them and have not had a problem yet...

Well it is the head gaskets. I'm going with ARP's and it's under warranty, so Ford's head gaskets=free or Black Onyx=$200. I just wanted to know what everyone's opinion was on that?

Free is better than $200. You won't have a problem with them if the job is done right. My truck has OEM gaskets in it.

[scparrish]

OEM! I read on here about some people having issues with the black onyx. Something about the cylinder holes being oblong

Mine are OEM and have been studded for over 70k miles.
