Mine aren't blown, nor are the heads warped. I'd just like to replace them. If I can get ahold of both kinds, I'll see if the later ones are thicker. I haven't asked on the Vauxhall forums yet.. it's possible that they would know if something like this could be done. I was curious since the 2.2 OHV in the S10 can have the later MLS gasket installed, and it pretty much fixes the head gasket problem the 94-97 2.2 had.
It's just that iron block/alum head engines scare me... I had a '94 Century with the 3100 that blew a gasket, and warped the head so bad it had to be replaced, and then my mom had a '91 Found On Road Dead Thundershit with the 3.8, and that sorry excuse of a car blew the head gaskets every 30,000 miles.
