You can run roller rockers on the early heads but check and make sure the pushrod slots in the heads are not worn. If it was me I would go ahead and put guide plates on it and drill out the cast in slots. That way if you have a problem and wear out a slot in the plates its simple to replace them. If you wear out a slot cast in the head you'll be taking the head off to install plates anyway. But HEY,,, that's just me!
