Noisy Hemi valve train

[SwedCharger67]

A friend og mine has an original 66 Hemi-Charger. The current Hemi-engine is a 1965 model, with heads from 1968. The engine has the original mechanical flat tappet cam.
According to the service manual the exhaust valve clearance is supposed to be .032, intake .028
These gaps seem fairly big, and they seem to create a noisy valve train. Are these gaps normal and is the valve train normally noisy? Can anything be done to the noise?

That's the correct gap & yes, they do make some noise. If you don't like the sound, the only way to solve that "issue" is to install a hydraulic cam & lifters.

Hemis aren't for sissies.

Any Car show/Drag race, I ever went to, in my lifetime, where there was a 69 and older Hemi Car, the Valve Train noise was prominent.

I ran my stock rockers at .016 intake and .018 exhaust and it reduced the noise level dramatically.

I'm jealous, I wish I had a Hemi to complain about....lol.

I'm pretty fortunate, I've got more hemis than cars to put them in! Lol

Oh My God! Where have I gone wrong in life?

I dream of an excessively noisy valvetrain.

Yes, the valve train is a bit noisy. I call it the solid lifter symphony.

Now if you really want to hear valve train noise listen to a Ford 427 SOHC engine run - that is if you can find one.

You've just got to start livin' the dream.

Here is what that dream looks like when looking down the carburetors at WOT.

Reminds Me Of Some Of The 426 Max-Wedges And Ford 289/271 Hi-Po Engines That Had Solid Lifter Cams In The Day! You Better Love That Sound!
