Post subject:  i keep getting a leak in the same head gasket

Well I just road to work and my center cylinders is leaking again. :banghead I have annealed it and retorqued it twice in the last month or so. Last time I checked the head with a straight edge and it was not warped, but I didn't check the cylinder deck.
It always leaks from the front edge. I torque it down propperly.

Would over heating be causing this?
I have been fighting a losing battle jetting for the pod filters. But it is hard to tell because I end up messing with the jetting every other day, because half the time I feel the head gasket leak I end up thinking it is a jetting problem.

EDIT..
Ok so this is how I was deceived by lean jetting all this time.
First off I have never road a correct running H1 to go by.
Then I had the partially clogged pilot circuit in one carb. This was causing a different cylinder to foul a plug every other day. I guess it was picking up the work of the cylinder with the clog. So this made me assume I had a to rich problem. So after billing and dipping that carb. I am back to thinking these pods have me way lean. So I picked up some bigger mains and am going two see if that helps. I put duct tape on my pods to cover about half of them and I felt a good power increase so I think I am finally on track. Stupid pods!

Are you using any kind of sealer ? I use Copper coat spray and retourque after 1-2 heat cycles.

No sealer, but I think I am on the right track.

Using a piece of glass and some 320 grit sticky back sandpaper, I went through and sanded my head and cylinder surfaces flat. I was surprised how far from level they really were...
