my preference as well. i believe ARP makes 12 point nuts with a small head size if you need them. much easier to get nuts started on studs in tight bends than bolts [relatively speaking].
They do, they were easy to find but of course when I went to order no body had them in stock. Used all ARP stuff when putting the manifolds back on my 2.2, spendy but much less frustration using all reduced head size hardware.
