How does this affect the end of the engine/head? I am not versed in all of the different engines, but the 216/235/261 COULD be bolted up flat? Or is there a reason I would want spacers there? NOT being argumentative, just want to understand.
Is it possible to make an adapter just like the one Drew and 12port mentioned, that just bolts up flat to the block? Is there a disadvantage to doing that? The reason I ask is, there would have to be some sort of meteor hit me on the head to EVER need to do an engine that is not 216/235/261. If I ever DO need to do something that isnt compatible, I would spend the money to get ANOTHER adapter. No?
