There is a head gasket that I believe was pioneered in australia and guys are pushing big boost on them. They are a 4 bolt gasket, but the most successful I've seen so far have been with them used on 6 bolt motors with 1/2" studs........I'm talking like 45-50 lbs of boost. There's lots of info about them over on the bullet.
The only issue though is like I said.....there isn't a ton of people using them yet and you really have to pay attention to the combos with them. These are built motors likely filled with big studs on methanol.......so it's really hard to see how well they actually work by themselves. The gasket has been cut out around the bore and uses a special ring that sits inside the gasket bore to seal on the head.
The gaskets are getting high praise, but like I said, 40+ lbs of boost is nothing new so you have to be careful about doing the monkey see monkey do ****. There is a dude with a fox body that claims a stock bottom end (it has been extensively worked but uses stock components) that runs 40-42 lbs of boost on stock heads and cometics and has been successful so take that however you want...........
The key things that I see that most don't like to mention right away is that these big boost guys are using blocks that are full filled, don't run water, have big studs and run methanol as fuel.
