There both C20XE's.
One has a Dispack, the other has a Dizzy. Early one iirc also came with a coscast head which doesn't go pourus.
Also, the AFM's are different.

the x18xe1 is a far better option than the c20xe. same shafts, gearbox, mounts etc... and is pretty easy to fit. they make 140 bhp and 135 ft/lb with minor mods and are far newer and more reliable. a massive amount lighter as well.

coscast heads are just as likely to go porous. its all myths and rumours that theyre not. some early xe;s also didnt have a lambda sensor

yep...
very early one's had coscast & no cat- 20xe..
c20xe with a dissy & cat - had a gm head
c20xe with dispac & cat - very late one's had a coscast head too
all same BHP if you remove the cat's
late xe's have square tooth pully's, early have round tooth
cam cover's a diff shape on the later one's due to tensioner's
later dispac xe's also use a 3bar regualer, think the early is a 2.5 iirc

true, not hardly hear about it..
the porus head is usually due to tightening the head too tight after a head gasket change..
that's why vaxhall changed the angle tightening setting on the head from 90 90 90 (coscast) to 60 60 60 for a gm head
