Can it be done? 20V head on a 2.3 NG?

[Brady Moffatt]

Hi All,

Why would putting a 90q 20V head on an NG drop the compression so much? The
20V is a 10.3:1 motor while the 10V is at 10:1. Pretty close. Did Audi move
all the combustion area into the head on the 20V while the 10V had a more
significant piston dish? Possible, but seems unlikely to me since they're
both non-turbo heads.

Cheers,

so). You'd also have to work out the manifolds and there are some head
gasket differences but it has been done before.
