I conducted a highly technical test this afternoon by blowing (lung power) into both of the side ports. I was able to blow air into both ports, so my deduction is that neither circuit has a check valve in it. The master cylinder is for a 70s and 80 Chevy C20/30, and I agree that they would have had proportioning blocks on the brake system. I guess I'll need 2 check valves, since I have drums on all my axles. Thanks for the feedback!
