[Mgs] MGB Head gasket reuse anf head bolt torque

[Robert J. Guinness]

In reinstalling the head on my 1963 MGB engine I am using a new Payen 
Head gasket.  When I torqued the #9 head bolt it broke at 40 ft/lbs  (I 
used new studs).  I have 2 question:s  1. Can I reuse the new head 
gasket after it had been torqued to 40 ft/lbs?  2.  The manual says the 
torque is 50 ft/lbs.  Is that correct, or should it be lower?  Thanks
