Well, you can scratch the 58.5mm Nikasil cyl and the NCY ported head with SS valves off of my build. 
The good news is, my cases are at Syc performance as I write this.
My new NCY 62mm Nikasil cylinder and A 12 cam is already here.
As well as the new valves and seals for the home ported stock head.
