Hydraulic Roller Lifters w/LA Block?

So I'm happy to report that after many issues and much delay we finally got it on the test stand and fired it up for the first time last weekend! I was expecting more noise from the solid roller setup but it's remarkably quiet (even quieter than before) and runs beautifully!! Just got it back home today so I can't wait to get it back into the car. Couple recent pics:
