Thanks Zach, yeah I checked/ adjusted valve lash on all 6 cylinders on Saturday when I replaced the valve cover gasket. It should be spot-on now. I haven't driven the car yet with the new intake, but it already revs much stronger and smoother through the RPM range. Right now its missing quite a few vacuum lines and is surging a bit, so I'm trying to piece together the vacuum and crank case ventilation setup
