Torque specs. Vortec heads& intake

I'am installing some new Vortec heads on my 84 Z-28 it is a 350ci.motor. I have everything that I need to do the job except I need to know the torque specs. for the heads and intake. I don't know if they are the same as regular SBC torque specs. With the weird bolt set-up on the intake I thought they may be different. I would appreciate some info. NORT

vortec intake specs are 11ft lbs, they have a special gasket that you can *** up if you overtighten it, heads are standard I believe
