Advice about HMG! I'm new here

Hi, I'm new at this forum, so first, hello to everybody, I'm spanish so my english is not going the be the best... hope you don't mind it.
I just bought 92 7MGTE Supra, it has about 60.000 miles. I'm aware of the well-known head gasket supra problems... and I was wondering if I could get some advice about what to do first on my supra. I've read that Toyota never recognised a problem with the torque of the supra head bolts (heard they should be torqued on 72 lbls instead of the 50's factory...) and that they are very likely to have blown head gaskets. So I thought, the first I'll 'do with my car is replacing the factory HD and putting a HKS metal head gasket with ARP head bolts properly torqued. But now I see there are a lot of models of MHD, 2mm, 1.2 mm.... The supra's factory hd is 1.2, but I don't know if it would be better to put the 2.0mm hd to gain reliability.. even tough i'll loose some compression ratio. What do you think about eveything? Should I even wait and ride more miles before replacing it?
Thank you very much.
