hey,

what all needs to be done if you shave your head and get a valve job with a better cam and a "performance" head gasket installed? Just shim the towers and change the lash pads?

Make sure you check the valve to piston clearance, since it is reduced both by milling the head and by using a thinner head gasket. If a valve ever contacts a piston, its bye-bye engine.
The cheap way to check it is to put a piece of modeling clay on top of a piston, then torque down the head. Then turn the engine by hand through a couple of cycles. Finally, pull the head and measure the thickness of the clay at its thinnest point.
