1.8L head on 2.0L block

[jdbubb at ix.netcom.com (Dan Bubb)]

Yeah, I'm with you.
But, the answer is alot more complicated than that. If both intake and
exhaust flow were better on one head then this would be a no-brainer. But,
they're not and the magnitude of the pressure pulses and the resulting mass
flow in the intake and exhaust ports are totally different. So, the question
remains, Anybody got comparative dynos of the two heads?
