Couple of questions before bed that don't have to be answered this instance.

I'll be getting an L67, anything I should be especially worried about when looking for one?
Any parts that I may miss with this build that may not be bad to order ahead of time?
With mildly ported heads (mainly exhaust and intake runners, cleaning up cast) what size pulley should I expect to run?

Shouldn't be too difficult of a build, but I haven't dug into an engine before so this will be a first for me
