For the head bolts, you can get a 10-mm double or triple hex bit at most auto parts stores. The bit slips into a 1/2" socket so you can use your ratchet and torque wrench with it.

I was able to replace the cylinder head of my SDL without touching IP timing. I suppose it's worth checking just the same.

oldsouth, do you mean the A-B light tool or the timing lock tool?

I used the A-B light tool. When I had the head off, I turned the engine over several times with the crankshaft looking in the holes and measuring piston clearance. My timing was off a little upon re-assembly.

You can just replace the gasket without removing the cam with a long socket, but if I went to the trouble to take the head off I would remove the camshaft and have the head gone over. How many miles are on your car?
