Default What is my compression ratio?

I need to know my compression ratio to buy new head gaskets; I don't have an engine code (it was the only thing "conveniently" scratched out on my engine label) so all I really know for sure is the ECU code that runs the motor:

Fineline imports said it was a "1999 V5". The ECU code appears to be for a V5 Type RA. The redline fuel cut is 8000RPM. I am guessing it may be 9:1, but I have no way of knowing for sure.
Help please?
