Last Checks: The rockers have the grove in the middle aligning the hole. Then they are correct for the 55 block and 55 head. Attached is a link to a video of the rockers working.
The carb (Weber 38/38) was cleaned and all jets and passages blown with compressed air. It now possibly smokes less, but still runs rich. I can see fuel driping into one of the carb barrels at idle. The other barrel seams dry.
