1970 340 oil pan gasket help

I just want to get some advise on installing oil pan gasket onto a 1970 340 engine. The crummy cork gaskets are junk! does anyone make a rubber style gasket to fit this? what torque values does anyone recommend for the oil pan bolts where it will not crush and break the &^*ing cork ones? Using factory specs and the gasket crushed and broke. I am sure it is going to leak so before installing another one hoping someone knows if there is a better alternative to the cork one.
