The Holley covers are real nice, LS9 style coil mounts-- great price too. They fit LS2-7 coils only (LS1 coils are slightly smaller). http://www.holley.com/types/LS_Valve_Covers.asp

I have a set of these GM Bowtie VC's I got from SDPC. I run YT Ultralights and no problems.

They look like this now.

Thanks! The engine looks much better with more light. I corrected the post to say "no problems".

Both VC's are vented with AN fittings and run into the bottom of the 4" downtube. No baffles in the VC's and the intake stays bone dry.

the Holley VC look so plane. if you like those, save some $$ and get the LS9 valve covers.

yes they are a direct fit. SDPC is selling the VC with LS9 coil packs and the harness adapter. so what you get is a nice new VC, new coils that mount via 2 bolts only instead of a nasty bracket and the harness you need to make them work. do a search, there are threads on here all about it.

Katech makes some nice looking valve covers.. you will pay $$ for them though as with all their own parts they make.. but very nice nonetheless.. probably the nicest by far that I've seen

For the price its really tempting but im not sure I want to mess with the problem of leaking if its true. I really like the mast covers but I cant get any one to answer the phone with mast and there website doesnt state how much. Im willing to pay the extra money for something that isnt going to leak, look good, and clear all aftermarket rockers.
