I'm working on a head program for guy here in SD. He had a similar problem I believe a member here had, and that was his chambers were too small for his 2056cc engine. (edited, he's using a 71mm crank and 96mm slugs)
Facing large barrel shimming, which he didn't want, I worked this up for him. perfect 60cc chambers, his non 2.0L heads will now install with a .045 shim , he has a zero deck, giving (I believe) a 8.5:1 compression ratio. This method of modifying heads results in perfectly matched chambers (and ports for him), so when he gets them back they will technically be blueprinted to within .001". not a 2.0L head granted, but thats sometin else and this is within his budget.
