Well hello everyone, This is an awesome site, so much information!

Well, i'll start with the questions i guess.
I've got a 327 thats had some mild mods done to it, but i have a problem with my rocker arms tapping away on my valves stems. I've adjust over and over and over, but it seems that within a mile down the road it's back. Any suggestions?

Also, i've got an edelbrock 650 carb feeding it, how might i go about adjusting the 2 idle a/f screws on the front? All i smell when she idles is raw fuel, granted i LOVE the smell, but i'm running a bit rich i think.
