What lift is your 224/230?

Are you going to be getting any numbers any time soon?

Your help is really appreciated.

Very nice, those torque specs are always very good to have handy instead of searching online with greasy hands.

Shoebox,
I believe you have the LT4 rocker covers. Mine sounded almost louder, different, weird. I don't know. Give me your thoughts.

I ran the Pro Mags before I put the cam in and had the stock covers on for a while. The LT4 covers did muffle the high frequency part of the rocker noise (as you would expect with the non-metallic material), but I do still hear them. It's odd, because I have seen posts with people saying their Pro Mags are quiet. I am sure it is a relative term.

I am chasing a little "clickyness" I have around 2000-2200 rpm. I am probably going to add a little more preload next time. At certain rpms/speeds, I don't really hear them at all. I guess other noise drowns them out.

When I put the rocker covers on I also changed my my exhaust rockers back to 1.5's, experimenting. My daughter, from the house says what's the matter with your car. Coming from her, who cannot change her oil, gave me reason for concern. Anyway took it out, ran good. I cannot believe I set the valves wrong, I've done it a million times. Anyway thanks for your thoughts.
