Assuming the timing belt is still broken/potentially damaged valves, unfortunately you can't do a compression test to see how good the cylinder condition is, as far as cranking pressure.
Unless you know how well the service was kept up with, at 180,000 with R/T gearing, the internal condition of the engine is anyone's guess, so pulling it and giving it a good inspection is probably the best route.
Don't let good looking cylinder walls fool you though. If they spec out good, hone them, and at least install new rings. You can pick up new pistons (aftermarket) for pretty cheap though. If you are keeping it N/A or stock compression ratio...
The DOHC that was in my '99 had near zero compression for #1 cylinder, Everything looked to be in nice shape, valves were sealing, nothing ugly going on with the cylinder wall, piston looked nice. The only thing I can figure is the rings were worn enough they weren't pushing against the cylinder wall well enough anymore.
The blocks are pretty tough, and don't generally develop much ring ridge. That engine had 236,000 miles on it, and the pistons pushed easily out the top.
