That's quite a bit of work. You've gotta drop the motor, pull the valve cover, pull the cams, pull the head, then re-install it all. If I had a full shop with full tools to do it I'd say that's a solid 8-10 hours of work with no breaks. That also means new coolant, new oil, new crush washers for the exhaust, new head and valve cover gaskets, re-timing the cams, might as well do a valve job on the new head to make sure everything is good and in spec, get the new head's cylinders honed, new rings for the pistons.
Sorry to hear about the misfortune man. Cracked cylinder heads suck.

Damn...sounds...fun... The cylinder head alone is going to run me $200-900 depending on the condition of it and if valves are included. I need new clutch disk also so I think this will be a winter long project. Thanks for giving me an idea of what I am in for.

FWIW it's seriously doubtful your valves have been damaged, so you can always swap over valves (just make sure to get new valve guide seals). I'm sure someone around here has a valve tool so you don't have to buy one to swap them out.

I think it's easy so long as you have plenty of time and $. Pull your head and take it and the new one to a machine shop for the prep work. Mostly just a parts collection project, and don't pull the cylinder unless you want to double time and expense.

Thanks for all the input. I have about 23k miles on her, is there anything else you would recommend on cleaning, replacing while I have the bike torn apart this much? I am going to replace the clutch disk and maybe basket I think in the process of doing this replacement. Also am turning her into a track only bike so I will be putting on my race body work and safety wiring everything.

If you're going that far, take a good solid look at everything. Check the play in the connecting rods at the big and little ends, take a glance into the crankcase to see how it's looking. Might as well take a good hard look at your transmission while everything is apart.
