Dave,

Thanks for info on what's available from Egge and your thoughts on the noise.

I took over the car's restoration from the prior owner who had the engine rebuilt. It has about 10 hours on it since the rebuild.

When I started the car is when I first heard the noise. It ran with a rough idle. I did not rev it up or increase the engine's speed. I shut it down after about 10 or 15 seconds. I restarted it and it seemed like the noise was coming from the rear of the engine around where the tappets and rocker lever are. The noise would briefly disappear and when it did the engine idled smoothly. I only let it run for about 30 seconds and did not rev it up for fear on creating further issues. I also noticed that the aspiration noise through the carburetor was different when it was missing and not missing, which might indicatate a sticking intake valve.

I have pulled the manifolds and the mechanic had several C Clamp spring compressors. It seems that the other style would be a better choice and I have one coming to me that I found on EBay. .My plans are to pull the rockers and inspect them as I do not want to damage the cam. What I find there will determine if I pull the head and check for issues with a tappet or valve.

When I remove the rocker arm assembly\ies do I need to be concerned about the tappets falling through to the bottom of the engine?
