Cold compression readings?

[Baltimore Sailor]

I've just replaced the head gasket, but the engine won't start now that I've put it all back together. It looks like I'm getting gas in there OK, so I'm going to concentrate on the ignition and the compression. What would be good cold compression readings for the cylinders to let me forget about that being the problem?

Thanks!

Around 85 psi or above. Actually, an Atomic 4 should start with compressions as low as 50 psi, but it won't have much power.
