Cylinder head center bolt access tricks wanted

3/8" drive , deepwell socket , turned down. Worked on my sbc, and my alum. head 440/505. Gotta be a way! I even remember prying the springs over a hair to spread them. They usually will move some in the heads spring cups.

I've got a Snap On 3/8 drive deep socket I use if needed ...and/or using ARP head bolts...
