should heads be installed with studs or bolts?

Studs clamp better IMO, but I went with the spec bolts to make sure I could remove a cylinder head "in-frame" if ever needed. It's personal preference in this area.

I did studs, but beware that any exhaust headers will need to be modified to fit with head studs.  The lower studs will hit the header flanges.  Not sure about stock exhaust manifolds, but TTi and Doug's both had to be modified (grinding the flanges).

Good point! when using studs, the nuts stick up higher than bolts so they may interfere with headers or stock exhaust manifolds. In that case grinding for clearance will be necessary.
