Here is a quick ho-hum summary on what has transpired over the last month.
Valve arrives March 11th. Said valve was unwrapped and dimensionally correct but obviously different (See attachments). Retailer offers to exchange with a 3 month lead time. SuperTech offers to exchange the valve free of charge so that I have 8 matching intake valves with a 1 week lead time. Valve for exchange arrives at SuperTech March 23rd. March 30th, SuperTech states that the valve shows signs of being lapped and installed, so the exchange is invalid, but will contact me once they have a valve made and reach to ship.
I did take the head, seals, retainers, springs, keepers, and exhaust valves to the machine shop. The head has been decked and the oversized exhaust valves are installed.
We are just in a holding pattern until I have a complete set of intake valves...
