Dumb question, cold starting...?

It's an oil accumulator. Canton make s nice one too.
The thing is at least for me, it's the bearings that I'm concerned about. I have a mini starter and it can develop 50psi cold on it's own. For the OP, the lifters would be pressure fed too (in terms of ticking... i.e. valve train slop). I don't think it matters much either way for lifter noise. So long as it goes away quickly, no problem.
