Can you explain a little more so my simple mind understands !You wouldn't drill through the bolt would you ? That's what it sounds like to me !!And flooding the top end ? Yeah I know,I'm not very knowledgeable in this field !!

well in the oil mod guide it shows him drilling thru the oil galleys...

one thing he is doing is slightly enlarging them but also removing any burs that hinder flow...

but if you make it flow to much to the top end you are starving everything else...

and what bolt are you talking about??
