HI AT THE MOMENT I HAVE A 12G940 CYLINDER HEAD ON MY COOPER THAT SEEMS TO HAVE BEEN MACHINED SO IT WOULD TAKE THE LOCATING RINGS WHICH ARE SOMETIMES INSTALLED ON THE FUEL INLET MANIFOLD. HOWEVER MY INLET MANIFOLD HAS NOT BEEN MACHINED SO IT CAN TAKE THE LOCATING RINGS. WHAT I WAS WONDERING WAS BECUASE I HAVE NO LOCATING RINGS FITTED BUT MY CYLINDER HEAD HAS BEEN MACHINED FOR THEM, WILL THIS MESS UP THE FUEL FLOW INTO THE CYLINDER HEAD BECAUSE IT IS HITTING THE GROOVE WHERE NORMALLY THE LOCATING RING ARE? THANKS

It won't make any measurable difference so long as the manifold is mounted so that the matching holes are as concentric as possible. The problem comes when the manifold slips and the holes ae not properely aligned.

OK THANKS FOR PUTTING MY MIND AT EASE, I WAS GOING TO PAY TO GET IT MACHINED BUT IF ITS NOT GOING TO MAKE ANY DIFFERENCE THEN THATS MONEY SAVED

As above, it won't make any measurable difference. You might want to turn your caps lock off on your keyboard though ....
