Weiand Tunnel Ram

I have used 3 weiand tunnel rams and I took a grinder to everyone of them and gasket matched the top to the bottom. I think more ppl would gasket match all intakes if the could see the problem with miss matched intake ports as easy as in the tunnel ram . The old DC motor manual says its a must to get the maximum power out of this intake thats why its so hard to find one that hasn`t been ground on. It took me years to find a low deck TR for my car that wasn`t ground on mainly because i would rather be the one doing the grinding
