Dismantled my LSJ (= Saab head) yesterday and although the LSJ exh. manifold had an EGR channel, the head indeed has no EGR system there. :-)
But as said in a different post, I was surprised to see the small dimensions of the exhaust ports. The inlets seems normal size for a 2.0, but the exhaust ports are really tiny. (Gasket has several mm's "headmeat" around.) Has the Z22 head the same small exh. ports??
Porting seems mandatory here for some decent horsepower. What is the experience with this? (Vocky? I remember Dude worked a lot with Saab heads)
