cam gear removal
What a PITA !! This has been covered well in other forums, but just to give my two cents.....

I pulled and broke down my shot motor today to get the heads sent out for machining. The cam gear removal is a bi-atch, but doable with a 1 1/8" box end on the flat spots on the exhaust cam, and a 24mm box end on the square end of the intake cam. I tried a 10mm hex socket with a 3/8" breaker bar and shrapneled it on the first try. Fortunately my 10 mm L shaped allen wrench help up to the 6 foot cheater bar with all of my 165 lbs hanging on one end to break the damn things. The last gear was trickier (right side intake) and I ended up using a chain wrench around the gear and let the handle rest up against the coolant inlet. Don't bother with the expensive Subaru cam gear sprocket wrench option, as I can't imagine it would hold up to amount of force it takes to break those allen bolts. BTW, the 6' bar came in handy on the head bolts as well.
