Just opened new Indy aluminum block and it is the same as heads
They make TWO passes across the deck surface of the heads and blocks--OK if they were same level but they are usually off over .003 leaving a nice step or whatever you would call it--Funny on this new block they even MARKED it as you can see in the photo .0035 how sweet! Most machine shops on earth make one swipe and get these critical surfaces level--just basic" machine shop 101" I guess they would argue that you are going to deck it anyway why not? after spending all that loot you might as well right? I guess not so important on the block as you very well may deck it but on the heads --just does not make any sense to me. Come on KB get those blocks shipped!!! They are a coming Boys--they are!! Yahooo!!

I do have to say these look a lot better than they used to but if a machinist student turned that in he would flunk right?
