BBC Chromed Rocker Covers (valve cvrs)

[Dicky]

Hi guys, I have a question about chromed rocker covers and what determined which BBC got them. My lowly '66 SS 396 Impala had them, yet I've seen plenty of 435hp 427's in corvettes for example W/O them (just painted orange). I for the life of me can't remember what came on my '67 L78 Chevelle from the factory but it was heavily Day 2'd. I do believe they were chromed at delivery.

Thanks for your help.
