A -12 AN bulkhead fits the stock valve cover hole size perfectly I think it's 1.25 IIRC. I am running a single puke tank routed to one valve cover with an oil fill plug to seal the other. The crankcase is common from bank to bank, so I think I should be ok. -12 is huge.
I read that bible too, and it helped make sense of it all. I stalked build photos on DSE's site and saw they consistently used one puke tank, so I figured if it's good enough for them, it's good enough for me. Simplifies plumbing and reduces cost, too.
Hopefully it works well. I'm still in the build stage.
