I made a bunch of asphalt panels, these can be used as covers it says. I was being cheap (and had the spare iron) because i wanted the most out of my asphalt. But then i quickly got sad because i can’t place them on anything inexpensive… So my questions are: Is there a cover accepting block that…

Plastic/Rubber/Wood Pipes and Red Alloy Wires would come to mind for that purpose. But I would highly recommend just using full Asphalt Blocks for that, just because performance.
