ARP Head stud nut clearance with valve springs

Sean Mooney said

Yes I noticed none of the studs are cut for oil clearance in the head. Will this be an issue with the Brodix small block heads?

It is a possible issue for any head. The .500" dia stud shank is a lot larger than the .44" (or is it .42"?) reduced shank of the head bolts. No issues have surfaced that I am aware of however. This is probably because even with the reduced flow area around the stud, it is not the smallest restriction in the oil flow path to the rocker shafts; that spot is usually up where the shaft bolts down to the rocker stand carrying the oil up from the head.

If the Brodix clearance holes for the bolts/studs were smaller that the clearance holes in the stock heads, then maybe more thinking and computation of flow area is needed. If the same size, it looks like you will be OK. So I'd check a stock hole diameter at this point and compare to the Brodix's.
