I would at the minumum go the stud route over the bolts. I have heard of guys using oversized studs, but know nothing about it.

I think that the bolt would be fine. I mean, you are talking big power, but not huge. The studs will just make it easier to change your heads after you pop something with that 300. I have seen procharged cars that were making mid 600rwhp using stock headbolts. But if you want to do it and do it 1 time I would stud the whole motor...mains and all.
