Good question, it used to be the thing to do. But some have proven its not needed and the 3/8s pickup is fine.

I have seen pics though where it would be benificial to port match the pump to the block. In some cases some very bad mismatches.

The 1/2" oil pick up cant hurt though IMO

But is it really needed, probably not. I guess I will find out as Im not using one on my new build.
