So, I lost the spec sheet on how to install my head studs and my builder is ready to install my cylinder head onto my built shortblock. I was hoping maybe someone on this forum purchased DHM head studs and could post pictures of the sheet with the sequence and torque specs.

Thanks in advance!

I found one on eBay and he posted instructions in the description.
Can I install these without removing the cylinder head?

Yes, However you must remove one bolt at a time in the OEM sequence and torque the stud to 70ft/lbs. Once all studs are installed you must loosen one nut at a time in OEM order lube it and torque it to 70ft/lbs just like in the instructions.

NOTE: Make sure that no fluids are present in the cylinder head bolt threaded bores.

Torque :
Stage 1: 44 lb.in (5 Nm)
Stage 2: 133 lb.in (15 Nm)
Stage 3: 26 lb.ft (35 Nm)
Stage 4: 90°
Stage 5: Tighten an additional:: 90°

This is the spec from ALLDATA, not sure if the DHM studs are different.
