So if you were to use a 1.8 head on a 1.6 block, this would raise compression?
Is there some sort of whitepaper or write-up on this? He's actually asking the question for me. Im curious as to how it lowers compression. I always have been told it will raise it.

The actual combustion chamber in the b16 head is larger than the b18c by a couple cc's.
However the b16 head is supposed to flow the same as an ITR head, so it's a trade off of flow characteristics for compression. You can always shave the head or run a thinner head gasket to bring it back up.
Not too sure on a b18c head on a b16 block, haven't really heard of anyone doing that. Not saying it hasn't been done, just that I don't know anyone that's done it.

Don't remember where I got it, It's in my head now.
If I find it again I'll post a link.

simple... b18c head will lower compression and b16a head raises... no matter what block the b16a head will be lower than a b18c... but this is good for turbo cars... like me i have a `97 GSR head that i want to trade for a B16... this would make the guy with the B16 have higher compression... this would also give me lower compression... so it is a win win if you find someone to trade like that...

u definitely said that first line wrong keith.
its very simple...the combustion chamber in a gsr head is slightly smaller giving the air/fuel less room to combust causing more pressure in that area which will yield a higher compression ratio.
