The FSM gives a new cylinder head height range to a couple thou. I'm wondering where I make this measurement at! (obviously one side will be the deck surface) Doesn't say where to measure it. This is to determine how much a head has been decked.

B18C new height is 5.589" - 5.593"

Its not from the deck to the valve cover mating surface. Thats about an inch taller than the specs. Any ideas?

 

It's probably to the mating surface of the cam caps. You use a large micrometer to get deep into the head....pretty similar to one you would use to measure the deck height on a cylinder block.

It can also tell you if the deck is parallel to the cam caps.
