Well I quess the upper needs to come off and check the inside of the valve cover for the rubbing to eliminate that or come up with the problem. I will check the rockers also for scaring and see what I come up with. The sound is killing me. The power is there, but with the valve train sounding like that I'm looking for something to be coming thru the hood every time I stomp it. Update soon. Just waiting to see if it quites by rubbing a hole in the covers or getting metal in my oil isn't a good solution in my book. I just live in Alabama not born here.

As far as the "self-clearancing rockers," that was pretty much a joke; however, I did have a loud set quiet down after a test drive -- not sure if it was a slight clearance issue or just stuck lifters that need to be broke loose, but it worked. I agree with pulling the valve covers and seeing if there is any evidence of them rubbing, but here's another thought. . . I've never used the chrome valve covers, but I wonder if it's possible that they may amplify the valve train noise more. Since aluminum is a lot softer (and thicker) then the steel covers, maybe you're just inherently going to hear more of the sound coming through.

No harm meant on the Alabama joke. Spell checker is for the weak. Grammar is for the educated. O.K. so I lucked up and got the valve cover off with out taking the upper off(sweet), but no evidence of rubbing. I did notice that there is some play in my push rods up and down? So now I wonder if I was suppose to change my pushrods with the head change? AFR 165? ANYONE?

I would imagine the stock length pushrods should do fine, but I've never had experience with pedestal-mount AFR's. Lee used stock pushrods on his, but his were stud-mount.

Double check your adjustments and/or shimming. I don't remember which cam you are running but it maybe that it has really fast ramp speeds and that seems to make valvetrain a little noisier or at least it did in my car

Well found oput the problem. Pushrods are too short. Factory is 6.243 and I had to go with 6.300. only .60 but that is a huge difference. Got the new ones last night and going to install tonight.

always check locaton of the roller tip on the valve stem. A little difference makes alot of racket.
