When reassembling the head do a dry assembly first without the gasket in place
This gives you the opportunity to make sure that the studs have not been streatched to the point the the nuts will get tight by bottoming out on the threads
Now disassemble and insert the gasket (with or without gasket goo) and then reassemble and add lube to the studs nuts and washers so that the torque applied is truly imparted to the stud and not absorbed by friction on the threads
When all done retighten all nuts as specified then run the engin for a short while then retighten again. Run the engine again and retighten again each time at the specified setting
You can’t retighten to many times
This method assumes you have made sure that the head and block are both flat before you started the assembly process
