90 lbs on the head bolts. I would use the Felpro intake gaskets that are black fiber with the blue borders around the ports (might be printoseal?) & spray them with Permatex "high tack" the red stuff in the spray can part # MA99 iirc. I would not use the front/rear supplied gaskets & use a wide/even carefully placed swath of silicone instead on front/rear surfaces surgically cleaned with brake kleen or similar then after torquing the intake let it set up overnight.
