Front jug squeak

Front jug squeak
I've been hearing a squeak off and on around 3000 rpm since I got the bike. I finally decided to locate it with the old tube to the ear trick.
My conclusion is that the noise is coming from the back left corner of the front jug where the head bolts to the cylinder.
Blown head gasket? loose head bolt?
Not sure what I need to do here.
Any suggestions?

Dang Spanners, where do you come up with this good stuff???
I don't smoke, but I drink, so i'll pick up some papers next time i'm at the liquor store.
I did look for residue around the head gasket area but looks clean. Shoved a rag in between the fins and not much on it.
Am I askin for trouble if I check the head bolt torque?
Thanks.

However, the chirping would show up with the paper test....the other cause of chirping can be exhaust gaskets or exhaust heat shields.
I wouldn't go fiddling with the head torque just yet.

The heat shield brackets, the ones that the hose clamps go through, are prone to cracking, so give them a thorough examination.

Removed all the heat shields and found that the noise is amplified by the shields. I plan to put them on one at a time in hopes to find which one is the amplifier.
It passed the paper test. Couldn't get any movement around the head gaskets or the exhaust pipe joints.
I think I'll do a leak down test just to be sure on the cylinders.
So the search continues.
Plan on getting loader pipes at the swap meet next weekend, maybe that will fix it.
