need opinions on this headgasket

[usetaboost]

I have an 82 block i'm building for an 87 turbo buick. I already have the turbo crank and pistons in. I want to use the 8445 heads. These are the headgaskets I got with the kit. I don't plan on racing this car anytime soon. pretty much all stock. Has anyone used them? http://www.gnttype.org/forums/showthread.php?t=6488
