Default Vortec head question

Guys,
I've installed vortec heads on my 79 about 1 year ago. Now I have a head gasket leak. Is there a special procedure to torque down the heads that is different than regular old 79 stock heads? Can you recommend a good head gasket? Any help would be appreciated.

Thank you,
Tony

i've seen re-conditioned vortecs on ebay that were beefed up in the crack prone areas.
