Ok,pulled the heads to have them gone through and cleaned up a bit. Was running a Ford motorsport gasket that I got with the rebuild kit last winter. They held up fine but now the heads are off and time to decide,was looking into the fel pro 1011-2, but had some guys that run boost recommend the 9333 which is a cheaper gasket. Any experiences out there? I have used the 1011-2 in another situation without a problem but these guys swear by the 9333. Also opinions on switching to head studs? I run ARP head bolts now but thought with my application maybe studs won't be a bad idea. Thanks in advanced guys.

broski, id have to say if you can front the money get a cometic mls but if your gonna go felpro id stay with the 1011-2

Only thing I have read about the cometic mls is the deck surface has to be prepped correctly for them,heard a lot of guys using them with out that and there leaking like crazy,Iam leaning towards the 1011-2 though.

yeah you gotta clean that deck and head area up really good

I just switched FROM the 1011-2 TO the 8548pt2's, which are similar to the 9333's.

The 1011-2 blew on my n/a motor when it leaned out while trying to tune an eccentricity form the engine. Never detonated at all, just leaned out and stumbled for about a second and it took the gasket out. The 1011 series are known for being very intolerant of tuning errors, as well as having coolant leak issues. Though I had no problems with mine for a long time until the lean out.

The 9333 and 8548 series are designed with an MLS type core for strength, but use a standard composite/graphite material to avoid sealing problems. Tons of guys run both on high performance engines with 0 issues.

You could also look into the SCE gaskets, or the SCE Titan if you have money. The Titan is a newer type of copper gasket that uses built in sealer technology, kind of how the 1011's have the beads, to seal the coolant passages. It's evidently VERY tolerant of sealing imperfections as well as being nearly indestructible. The Titan also uses a built in combustion seal that functions much like an o-ring, but it's all in a gasket that you just slap on and torque down basically. But they're nearly $200/pr at Summit

friend of mine runs 9333pt1 on a turbo motor , I run 1011-2 on my 347 with a 100 shot and no issues yet but the 9333pt1 gasket can be more forgiving with the graphite material which can allow some shift/stretch that occurs on force/bottle fed motors, I've used both with no issues, of course if you can stomach the mls gaskets, they are best

Hmm ok,I can't handle those Titan ones,lol,the only thing that concerns me about the 9333 is its .047 compressed,and the 1011-2 is .039, how much compression would I lose?
