Dual Springs Noisy?

Dual Springs Noisy?
Hello all,
Can you please confirm to me that dual springs make tapping noise ? especially at idle.
Is it normal?
Because it's really loud compared to stock. It sounds like the two springs are hitting each other for every dual valve spring.
Thanks

There are many contributors to valve train noise but most often the sewing machine noise is because the preload is off. If you take your time and get your preload to .080 - .100 you will have a nice quiet valve train. It won't be quite stock sounding but it won't clatter like so many do now.

I have a T-Rex with patriot dual golds, and mine is quiet. So I really don't thinik it is the cam. That has very aggressive lobes and lots of lift. I think you have more problems. I'm still thinking lifters. Have they ever been done?

My springs are quiet, but my lifters are suspect. Patriot Gold Duals here with a TR224 Cam on 7.4 pushrods. Looking to do a head swap soon so will see how the lifters are the cause or not.
