I'm surprised at the low torque setting. I always thought that the spec was something like 75 for head bolts and 55 for head studs, due to the fine pitch most studs used for the nut.
When I blew my head gasket was soon after I bought the car, and I found that the head apparently hadn't been retorqued after the gasket was changed, and most of the headbolts were hardly tight. I replaced the gasket with a FelPro (sounds like same construction as your Reinz) using Gasgecinch (sp?) on the copper side of the gasket, torqued it to 75 initially, then checked it a couple of times after driving for a while. Most of the bolts did tighten up a bit.
When I put on my Edmunds head I used the same gasket and process but with new head studs, torqued to 55 pounds, and have never had a gasket go. It normally runs about 200 degrees, and did see about 220 when I was experimenting with the timing curve of my HEI. When I pulled the head off for my latest upgrade project the gasket was in perfect shape.
