Okay, after finding out to leave the oiling hole alone on head gasket, I should ask if I should use restrictors in the heads. Rockers and shafts are almost new and I'm using a new Melling hi volume pump. The oil pan is a new Milodon 5 qt. If I restrict the top end, what do I use? does anyone make a restrictor for the FE head? does the hole have to be tapped or drilled for a restrictor? Saw one post that a split roll-pin was used. I would rather do this now before the heads go on so as not to contaminate the oil passages. The crank has been turned .010-.010 and new bearings so everything should be fairly tight which brings me back to the question of restictging the top end or not. Have a chrome set of "power by ford" valve covers if that matters. I trust your knowledge and that is why I am always asking questions on this site.
