SR20DET S14 Head Build, how would you do it?

[Ser200sx567]

Hello everyone I'm back Building an S14 SR20DET Head. I Just got it a couple of weeks ago and got it tore down. I have finished all but a little touch up work on the head porting and getting ready to order some parts? I had flow tested it and it's shows a 14% gain on the intake and 11% on the exhaust side. I have more pictures coming here is some I took of how its sitting now.

Parts:
Bronze Guides In shop
Stainless Valves 0.5mm over size in/ 0.5mm oversize ex with reduced valve stem dia of 6mm In Shop
Titanium retainers In Shop
HKS 264 intake and 264 Exhaust Cams IN SHOP
