After mocking up my heads to the block and putting .039 feeler gauges in b/w as a mock gasket. I have some disappointing results. From front(#1,2) to rear(#7,8) the molds get thicker. .060 front to .080 rear. So what do I need to do now? Have it block decked or heads milled at an angle to "true" it up so I can get the same clearance everywhere? Is it possible the deck is sloped? Im confused. Thanks.
