I guess it depends on your definition of "totally screwed".
Yes, pulling off the heads would be first step, but I don't think it will be the last step.
When crankshaft won't move it is usually a major issue involving pistons and/or main bearings, in either case block will need to be pulled out and crankshaft removed, to replace piston(s) and/or bearings.
One "good" thing is that the Vulcan 3.0l engine is very common so finding a rebuilt or used Long Block won't be hard or too expensive.
Short Block = crank and pistons installed in block(your heads could be damaged so..........)
Long Block = crank, pistons and heads installed, in/on block(you have the intake and the rest of the stuff so this is the best bet)
Complete engine = intake and most brackets and accessories included(unless price is right, and having back up parts seems like a good idea, you don't need all this)
