If you go for head studs, be sure you can slide the head off without doing a lot of extra work.

I assembled the 462" Buick engine in my roadster on an engine stand.

Not too far down the road I pulled the heads to machine for Teflon guides and different springs.
I found the right side head would not come off due to a conflict with the 32's sticks-out-a-touch front body mount.
Had to pull the ARP studs which isn't too bad, but the two end ones are down in a well.

Last time I had the head off, I stuck ARP head bolts in it.

Kinda funny looking, but no one has ever commented about the right side bolts and left side studs.

Sorta like my pal from back in the day, he showed up with his flathead powered 49 Ford coupe with an aluminum head on one side and a factory head on the other.
Ran ok, kinda made folks wonder though....
