Tell him 9.0:1. you won't know for sure, unless you measure it.
Things that could be different from standard;
Bore size (Has it been bored out?)
Deck height (Has the block been decked?)
Head cc (Has it been surfaced, if so how far from standard?)
Piston design (Has it got Valve reliefs or are they flat?)
Head gasket (is it a standard thickness?)
A good tuner should need that info unless you've done something crazy to the engine.
