Sorry, I had to go do something. Anyway, the allen bolts have a "captive" washer (I believe they call this a Simms washer). If you tried to use regular bolts and studs that use a flat washer this might end in a very bad way. On most of the bolts you are working thru the little holes. Won't be long before a washer falls off as you are taking the bolt out and you know where it's going. Bad day. But if you use the proper bolts, the washer is captive and the whole thing won't go in the cylinder. Mo better. It is best to torque the intake with the book instructions. (I know, nobody does it that way.)
