what is the part number on your heads, cause i have a set of the jrs on my car right now. they work good, if i was guessing their either the -1 or the -2. maybe even possibly the bare casting. they could have been put together after they were shipped. but the -2 heads were made to fit both style camshafts. so id trust the guys who sold it to you, it should pretty well.

pop the valve cover off and snap a pic of the spring. dead give away if they were purchased pre assembled.
