between 1.9L and 2.1L waterboxers. Are they indeed the same?  Are the
chambers the same volume? The 2.1 heads I have both have a LARGE crack
between the valve seats... ...larger, I think, than the Bentley says is
allowable. I have a set of "original" 1.9 heads from an '84 that may need to
go on in their place.  I do not want to raise my compression ratio - no
premium for me, thanks!
