Head Bolts too tight?

My 79 engine book said 105.

I just built an engine and torqued to 105, I won't be losing any sleep over it.

It would be interesting to know why the specs changed. I would imagine gasket technology has changed a lot since 1968. even from 1968-1979 that's a lot of time. Think about what has changed since 1991-2012? I guess that's comparing apples to oranges but you get the point. Some of you old farts might even remember 68-79.:D
