I would replace the oil pan, you can get a used one or buy a new one..its not hard to do.. because if its cracked then its weak.. Welding may fix it, but that does change the temperament of the metal..

But their is no gasket. They use Engine Sealant GM part #12378521 around the perimeter and the oil feed of the pan. The oil pan is hard as hell to get off, you might want a pry-bar. As for the torque specs, its 18 ft/lb. Fairly easy.

The heads will go to 7500...but there is no use.. the stock internals can not handle that long.. and the head its self does not flow enough to be making power at that high of RPM's..

Correct until 07:
Intake cam is longer than exhaust cam.
Uses “waste spark” control system, so there is no cam position sensor.
Intake cam is the same casting as the LSJ intake and exhaust cam, but lacks the pressed-in hex.
Compatible with GM Performance Parts adjustable cam gears.
Can be replaced by GM Performance Parts matched cam set (requires Bates Enginering valve springs and retainers to prevent coil bind) or other aftermarket cams from Comp Cams.
07 cams are different.
New intake cam has a wheel-style cam position sensor.
Intake cam is not interchangeable with any other ECOtec cams, nor with the GMPP intake cam.
Exhaust cam casting is the same as previous model years, with a slightly different cam profile
Exhaust cam is interchangeable with the GMPP exhaust cam (requires upgraded valve springs and retainers).
Compatible with GM Performance Parts adjustable cam gears.

Weld it, or buy my spare oil pan, it has no cracks and has 40k on it.
