Head gasket getting oval?

I drive 98 to 100 octane no race fuel, yes using washer under the head bolts, the threads in the block are clean, there is no dirty or something like that, i run 34 degree timing, the intake ports looks oily on one head and carboned at the other one, but as i told to my friend that i open the bolts from the heads was not really hard with my torque wrench he meaned that my torque wrench maybe is the problem but i will check that with another one tomorrow with my friend, and guys really thx for your help, but i dont knew much about the inside of the engine, that why i will go to an engine builder on thurdsday i will let you knew what we find out!!

thx Peter
