Stupid Questions

[drew at scirocco.cs.uoguelph.ca (Drew MacPherson)]

The DX is a European engine that had 10:1 pistons (from the HT/RD) but 
used the JH block and head.  In non catalyst trim the DX is good for 118hp 
at the crank, in catlyst trim 112 hp.

These heads will be interchangeable, like all 1.8 motors the block has the 
larger drain hole so you can switch back and forth between solid lifter 
and hydraulic lifter heads without issue.

The first head is likely from an 83 model year, the second head from an 85 
model year (based on ETKA's engine numbers)  It looks like the DX went 
with hydraulic lifters in '86 model year, so they're both probably solid 
lifter anyways.

Patrick is correct on ID'ing the hydro heads - they lack a number 4 
bearing cap.
