What was your close measurement? It's really hard to get much more that 1.725ish with stock length valves. I don't think I'm even at 1.700. That's one of the issues with OE heads. Then you add long valves and the geometry goes even more off the rails, and to correct it used to be a real mother bear.
That's why I never ran a roller cam on OE heads. You can't get the installed height to get the lift in there.
