12 Second N/A Slant 6?

I can't remember whether you raised the rocker shaft or shifted it sideways.

Without specific dimensions can you detail what was done?

I'm still leaning towards "metric" valves W/7mm stems, but longer stem length for more lift capabilities seems like a good idea.

Both. Moved the shaft closer to the valve tips AND raised it. He gets both movements from that one specific measurement he asks you to take. It has to go up because of the longer 318 valves and since the valves face away from the rocker shaft, as the shaft goes up, it moves away from the valve tips, so that has to be made up for. Do my best to get pics in a bit.
