The ZDDP problem is really a non problem as long as you are aware of it and use the right oils or additives to combat the lack of ZDDP.
I think what I'm gonna do is just wait till I see a good block pop up for sale. Roller or non and buy it. At this point I'm only stockpiling parts that are not roller/nonroller specific.
9 more months till the build begins!!!
