As above, you'll never get 10.7 static with a zero-decked flat top, without serious milling or a steel shim (and mashed valves).
You fluffed your original calculations by putting the valve reliefs in as a negative number (if using the kb calculator).
Run a .040" gasket, it will come in around 9.7-9.8 static and your motor will run happily on 93 or less. Those closed chambers with decent quench won't need much total advance anyway.
