Hemi Remote Oil Lines

I have noticed a few guys have said they are running 1/2 or -8AN lines for their remote oil filter setups. Is there any benefit to this? Wouldn't the flow be limited by the smallest point ie. the 3/8's (-6 AN) connection on the block so there would be no advantage in running a bigger line?

Here is what I am looking at ordering (I have based my order on others using -8AN line), from Engine block to remote oil filter: If I have missed anything, feel free to chime in as I've never ordered anything with these fittings.....
