In general, I have had good luck with both Victor-Reinz and FelPro gaskets. Some people seem to have a preference for one or the other on 6.9/7.3L IDIs and I would like to know why. Thus far, I am not hearing anything useful, just the usual "brand X sucx" and "brand Y is better than sex." I've got to make a decision soon and am updating my research. If anyone has any info good or bad to point me too, I would appreciate hearing it. Needless to say, I will be installing ARP head studs too. Last time, about 13 years ago, I went FelPro, when the engine had an external oil leak with the OE gasket (for which there were a lot of warranty fixes in that era). It may not mean anything, but in January, the engine suddenly and without warning blew the head gasket on #7, which in turn blew out the right-hand bellhousing freeze plug... which was solid and not rusty, I might add. Surprised a freeze plug blew before something else, but #7 was blowing out that freeze plug hole and making heap-big noise. When it blew, that freeze plug in the bellhousing made some noise too. Wouldn't you know it happened during a blizzard and it took two hours for the tow truck to get to me.
