What valves are you using? This has the Farrea 1mm over. What valve lash did you end up with for intake and exht? I talked to Farrea about the stock inconel valve VS their valves and they adviced me to go with Tomei spec lash. The few I did last time was with stock valves so there's no question with valve lash.
Is your motor out? There's only one way to degree the cam so I think you should have no problem, just gotta custom make some adaptor tools to work on the VG head :(
