We're discussing two different "restrictors"- - - -any muddying the water some more. The bypass filter standpipe has a 1/16" hole in it to restrict oil flow back to the crankcase. The cylinder head has a restrictor to control oil flow to the rocker arms. Discussing those flow controls in this situation is like comparing apples to Kiwi fruit! Neither one is going to affect oil pressure at the gallery that runs along the driver's side of the block, no matter how it's plumbed.
