500bhp what are the cometic ones rated to?
try running it, then leaving it for 10 minutes, take the plugs out, turn it over, and see if anything is spat out of any of the cylinders. might give you an idea which it missing.

yes I am going to leave it over night so enough of what every is coming in could be visible when plugs are out and hope fully the gasket is the only thing but could also be cracked head or cracked block
