Last I sealed the top of the engine I used Red hi-temp RTV.
It worked OK, leaked a little.
What are you recommending for that these days?
Also on the road it might be necessary to reuse a base or head gasket if the engine has to come apart and fresh spares aren't available.
Can you recommend anything for reuseing these and if so does the torque spec stay the same?
Should the head be retorqued?
Should the engine top?
