definately non-optimal.
advancing timing on injection can be tricky.. the dealy is more than emissions, it is to allow ecu to be the slow dummy it is...by up to 14 degrees. The carb cams, even emission versions... are advanced towards 3 degrees, because it is realtime. Errors impossible, gear driven distributor included.
I would love to know if this works, as I have two cams that are injected, and want the lift for my carb engine. I need to advance by 10 degrees to be normal.
also advance should cool down top end, injection plays with temperatures so something may go rich and ruin hypermiling...
sohc should be a rock and dymamical.
