that's how I read it. the next paragraph allows removal of parking / marker lights etc... and for the resulting holes to be patched over or used for ducting. popups have to have the lids down in order to meet the general bodywork rules but so long as they never come up, there's no requirement to have working or even clear lights in them.
I'll add a question: motor must be from same manufacturer and configuration (9.1.4.E.1) but must it have been sold in the US? in other words, could you use a JDM longblock and intake for an engine never sold in the US (like an RB series nissan)? Or one that includes components NOT open under the rules (i.e. intake manifold or head variant) never sold in the us on a motor that otherwise was available (such as 20v toyota 4A-GE)? of course this assumes a 100% adherence to OEM intake and throttle for that motor and other restrictions, and proof in the form of a service manual for the doner car. I don't see why not but I could see where one might have counter arguments as the STCS is just not specific about it.
