What Next? Cam Timing Question 107 560

[Strife]

Well, I'm in the middle of doing the RH head, and the timing marks on the LH cam, RH cam and the balancer were at dead zero. So, I remove the RH gear, and, surprise, the cam moves about 15 degrees to the right (CW) (7.5" chain stretch?). It is now in a position that I will not be able to put the chain and gear back on, now that I have replaced the tensioner arm and chain guide (the tensioner is NOT on). The engine has not been otherwise moved; the LH mark is lined and the mark at the harmonic balancer is a 0. I haven't touched the engine afer changing my pants.

Questions:

1. Can I turn the cam BACK to its original position at the RH line-up mark? Seems like this is reasonable (it was there before...).

2. How?

I don't think that I can use the bolt (not to go backwards (CCW), anyway).
I can remove the plugs to remove the compression
I can remove some (but not all) of the rockers.

I've been thinking of making a tool out of some strong bolts and metal, to put in the holes on the gear.

BTW, my plastic guides looked like crap (brown) at 87K, the arm had two good-sized grooves in it (original? the Swag replacement is smooth), and the tensioner was REALLY, REALLY loose (felt like just the spring in there before I took it off).

I'm really being cautious about the next step...
