Holley polished valve covers Just got these installed. With a '05-'06 LS2 GTO they will pop right on using your old gaskets and bolts. It replaces the large black bracket that sits on the stock valve covers and the coils then bolt to the bracket. It cleans up the bay and makes it so pretty you won't dare cover it with a plastic FRC.
We '04 people have it a little harder. The LS1 has coils with 65.5mm mounting hole spacing and the LS2 is 72mm just like the stands on the cover. I ground a vee on one end using a bench grinder and quenching the coil in water every 5 seconds to keep it from possibly hurting the coil insulation. The grooved end sits on the lower valve cover bolt and once the top bolt is in the normal hole you can't spin or move the coil. I used SS button cap screws with 1/4" SS washers. It pretty much makes it look like a slotted hole on the lower mount point. I removed and cleaned up all the old harness mounting tabs and the old labels for that and the injectors.
Very nice for $150 shipped for natural finish, $20 more for crinkle black or satin and $220 for polished (mine). BTW the oil breather is an add on. It has 1 1/4" threading on the cover and comes with a nice billet screw cap.

Looks great.
Would using a set of LS2 coil packs be an option? ( just asking..)
I got a set of the crinkle black valve covers and have been happy with them.
Im no good at keeping anything polished clean.

Ya I'm looking into picking up a set of cheap LS2 coils. You also have to have the two harnesses for the LS2 coils as the connectors are different. They're wired the same but the connector has a "key" that doesn't fit.

Well it was round 2. I picked up some LS2 coils with harnesses. So there's two ways to do it with a LS1. I painted the coils and wires flat black and popped them on. I found out you get one hell of a loud bang when you put one harness on backwards ;D.
