Dear all,

Could anybody please tell me the dimensions of the stock ls7 cylinder head in particular, its height (from the bottom block gasket sealing to the upper rockers cover).

Many thanks.

It's the same as all other OEM casting LS heads

And what's the height of the standard OEM LS head?

what makes the LS7 head different?

The architecture of the LS7 head is a bit different than the LS1,2&3 in that it's taller by almost .300". The rolled valve angle, longer rockers and tall intake port height all add up to the required changes that were made.
