On the 1:1 machines, the lift cylinders are t-connected together with a single hose returning to the valve. When the tilt cylinder moves, it forces one lift cylinder to extend and one to retract, with oil moving between the two via the hoses. No pressure relief valves are needed. (There are cylinder piston valves in each lift cylinder that have some effect on the oil transfer but should not cause a problem for normal tilt.) BUT, the tilt cylinder must have enough force to cause this to happen, that's why tilt cylinders are larger in diameter than lift cylinders. Maybe you need a larger diameter tilt cylinder?
