I just texted the engine shop and asked them for that dimension. I hope to get an answer this afternoon. The picture I posted is the engine they are just wrapping up now, my engine will be using the same heads and valvetrain. My engine is in progress but not that far along yet. We might be out of luck if they shipped it.
I don't much care for the price of those spacers or the extra joint to leak oil on the headers. I appreciate your suggestion of those valve covers, but since my heads are not AFR trhey would be inappropriate. I was hoping to keep it looking vintage under the hood, I really don't want the welded fabrication valve cover look. I suppose I could ask the shop to dial the cam back so I don't need the rocker stud girdle, but I hate to give up the power.
