Hmmmm.....good to know. I just bought an electric impact wrench and it took the bolt holding the pulley onto the crank right off, so I'm hoping that it will work wonders on the head bolts. Maybe I'll blast them with some PB Blaster and let that soak in for a bit. So far I've been surprised with all of the nuts and bolts on the old engine. I figured that after being together for over 130K miles they would have seized together, but everything has come off with no problem......so far.

Congrats, again, on the new ride.
