can you use an s14/15 block without plugging the vtc oil supply on top of the block ?
i've searched and found out that a couple guys using an s13sr20det head didnt plug it cause there is only a pressure of 10psi to 15psi coming out from that oil supply due to there being a restricter and once you mate your head onto the block with your headgasket ,it seals it completely ,what are your thoughts on that ?
