2.0L head being just plain newer than the 1.8L head, the 2.0L head is a
better choice you don't have to worry as much about the tensioner stud
pulling out or the cam bearings being worn so much, etc.  And this is
without even mentioning the fact that the 2.0L head has more material for=

porting than the 1.8L head.  See, even though the 2.0L head has smaller
intake ports it depends on how it is ported not necessarily how big but i=

does have larger exhaust ports so overall the 2.0L head flows better.  So=

you find a 2.0L 16v tallblock somewhere, just slam the whole thing into y=

car and swap the manifolds.

I wonder how this whole 1.8 is better than 2.0 thing got started?  Maybe
someone who ain't into 16v.  Hmmmmmmmm,  MEZE?????

HTH!!

i've been wondering about this myself lately. the head chamber volumes of=

1.8 and 2.0 heads are both 45cc. so the head doesnt change c/r.
the advantage of a 1.8 head on a 2.0 block is that the 1.8 flows better t=

the 2.0 in their respective stock forms. this could effectively make a
person think the engine has a higher c/r since it would get slightly high=

max pressure readings during a compression check.

Now that's the first time I've seen a number for the head chamber volumes=

stated when this topic has come up. (and it's come upo quite  a few times=

for who started the "1.8 is better than the 2.0 head", I doubt it was a l=

not running out to get another 2L head though.
