Back in 2001 I installed a "1.9" AMC head on my '84 7 passenger.  It's
still doing fine.  They've since discontinued the 1.9 heads and are only
selling 2.1 heads (no compromise).

2.1 heads can be used on a 1.9 as long as they're used in pairs.  When
installed on a 1.9, the compression is a tad less than if 1.9 heads are
used.

My Boston Bob 2.1 engine was fitted with AMC heads with different valves
and a special grind.  I carefully looked over the gasket area before
installing all the bolt on stuff and they appear uniform all the way around.
