Gasket blowout - pics

[burner31]

Blew out my exhaust manifold gasket, I'm thinking I may have over torqued the bolts...your thoughts on this.

I had 180 miles on those old gaskets.
I didn't use a torque wrench when I first put it together (still can't find it), but my wrists have been calibrated to within +/- 5 lbs...or so I thought.

I know, I know...I'm going to buy a new one this week.

And don't let the Chevy fender cover get to you, I use it on my '57.
