If it's your first time doing it, just make sure to read the Chilton's to the letter and set aside alot of time. You can probably get the head off in a few hours, but putting everything back together including the T-Belt will take you a bit longer just to make sure you have all your bases covered. Also, definitely replace the stock head studs with ARP's. It is absolutley worth the 90$.

Set aside more than weekend though, just in case, since we all know DSM's manage to make any job at least twice as lengthy as it should be.
