Comp Cams Pro Magnum 1.5 Ratio Rocker Arms

Just wondering if anyone who has these rocker arms had to shim the rockers to make them work? I am looking up the description on these and it doesn't look like they come with shims and Comp doesn't sell them either so I am a little confused. I bought some 440source rockers for my 440 and had to shim them to line up the rocker arms perfectly over the valve and am wondering if anyone who has these had can tell me if they had to shim them or they lined up perfectly over the valve without any shims? This is going on my LA 360 with X Heads. Any information or personal experience with these would be great. Part number is 1622-16.

Thanks
