This is really a neat build. Congrats on what you have accomplished so far.
It starts to get into some big money with these projects. The labor is expensive enough that cheaping out on parts doesn't make any sense. All you would have had to do here is send one of the old rods to Autoverdi and have them send you some new ones.
I expect the valve springs etc are similar. Hard to know what to trust. One hopes the cdi springs are a good enough fit to last.
