I bought a set of those but was very unimpressed with them. Had to redrill and tap them to fit my (truck) coils under the SB valve covers. The oil fill provision was ridiculous and there was just no room for everything under the vanity covers... And everything got packed so tight under the covers, I was concerned about the coils getting too hot. Definitely a failed experiment for me. The sbc valve covers did look pretty awesome on the engine though.
