    So far so good. I think I am going to go with the tap and drill method. I am confident the passenger side hole can't hit anything....as for the driver's side hole, I doubt it will hit any water passages or oil galleys either(assuming a reasonable depth) I cant imagine they would run differently in the ecoboost head vs the cyclone...and worst case scenario, even if I drilled into one, I could just install some thread sealant on the bolt securing the crossover down and it wouldn't be a problem....people plug oil galley holes with bolts/plus all the time in various head conversions without issue. The only issue I can see is getting the passenger side hole started correctly might be a bit of a challenge...since it falls on the slope past the machined surface as you can see in the picture....but that is the beauty of transfer punches...I highly recommend buying a set for anyone who does a lot of fab work...one of my favorite tools.
