Crank end play, destroyed converter, 408 nightmare

I have had issues with that head gasket. They say no need to retorqued the head. I have popped two of them at about 10:1, changed over to torquing them and letting sit overnight. Then back off a 1/4 turn and retorqued them one at a time in order. No more issues. Now I run cometics.

I built an aprox 600 horse sbc that I had trouble blowing good head gaskets on. Don't remember who told me this , but when u torque ur heads down in increments, leave the last one that finishes it, until the next morning or evening . Gives things time to relax , before final torque , very seldom have to retorque if ur using good gaskets. ----- Worked for me !
