Not sure I saw it mentioned earlier or not but the econo’s With built in pedestals came in short valve
and long valve versions. Which length valve are you trying? I have a long valve econo head here that uses the tall ~5.28” valve length and can measure the height of the pedestal if it helps.
That would be helpful, that was a 5.250ish valve stuck in there, but I think they are the shorter length version, the rocker is at quite a angle with the valve on the seat. Another good reason to mill that stand off and use blocks I'd say...
