I am running 205's with stock valve covers, although I did do some clearing work inside the valve covers for the rocker arms. I have several threads in the archives on my 205 setup preparation and installation.
I checked your profile and since you have a 97 you will need a later set of valve covers. I found my set with an 04 valley cover brand new on fleabay that were removed from a crate motor.
I was just interested to see if anyone on the forum was running these heads. I was reading the AFR catalog. I am going to do a HC package in the future. I have had people recommend all 3 of these heads. I understood the 210's were new just interested to see what people thought of them. Every vette shop has their personal favorites. I like hearing from the actual users. I am not ruling out anything. Trick Flow, Patriot any of them.
I have a 2010 Catalog and Tech Guide AFR just sent me. Doesn't mention anything about discontinuing the 205s. Doesn't sound to me like many people are using any of them. I am kind of surprised.
