i am working on a 2000 outback EL25 2.5L engine. I have removed the heads from the engine and I need to have the heads resurfaced. Before I can do this I need to remove the camshaft assembly from the head. My questions are as follows:

can I remove the camshaft assembly as one complete unit?

Do I need to remove the 8 stars bolts and the 8 allen wrench bolts that hold the two assemblies together?

Is there a pattern for unbolting and what is the torque for reassembly?

Any RTV required on reassembly?

I don't think you need sealant anywhere on reassembly except the half-moons and the oil pump. No sealant on any of the gaskets.

 

Yes the headbolts are to be loosened in a sequence, but I don't know the sequence. It's already been mentioned on here before, have you searched for any detailed head gasket information - there are some great resources online too - one by "Skip" i believe even?
