I plan on dropping the engine soon to do a valve adjustment and clutch, pressure plate upgrade.

Is it possible the shop didn't torque the headstuds properly, and if this is the case, could a re-torque remedy the problem, or will things have to come apart again.

Any suggestions.

I noticed you're using the '91 cylinders on your build. I have the same type of cylinders on my 3.3 w/3.3 heads. They're weeping between the head and cylinder. These cylinders have a habit of leaking (slightly), mostly due to the amount of surface area between the head and cylinder. I had a post on this site as to what can be done to remedy. Steve@Rennsport replied there's not much that can be done except to disassemble and and have the heads and cylinders ringed. He stated he's done this many times on these cylinders with fantastic results.
To rule out the rocker shafts, I pretty much used the ol' white glove technique. Use a white glove or white cloth and touch the ares outside the rocker shaft. If there's oil, it will show.
