I'm not using Edelbrock heads. I have the Motorsport A3 aluminum heads. I will have to dig out the 1983 catalog to give you the part number but the fastener kit that was sold with them is a BOLT KIT, NOT A STUD KIT.
I'm not exactly sure what the advantage to studs would be but the disadvantage is that many engine compartments are too tight to be able to remove the head from the block with studs.
The key to longevity here is the head gasket and torking the head down accurately to manufacturers specs. I seem to think that it is 110 ft-lbs for the Fel-pro but I would have to check. You have to use the manufacturer's number rather then the Ford shop manual number. Also of note that torque wrenches need to be calibrated occassionally. I will actually use two to make sure that they both agree in critical areas.
Just my opinion. I suppose the answer is what it is.
