Compression has very little to do with your engine's port. You can sometimes distinguish a ported motor from a stockport motor by vacuum readings at idle, though intake leaks and low compression can also contrinute to lower vacuum readings.
Bottom line, any healthy engine should make 100+psi of compression, ported or not.
