Lunati VooDoo Question

I am currently investigating a noise in my top end.. Sounds like a lifter or wiped lobe.

If I need a lifter I want to change all 16 and need advice on what to use.

If I have to change cams I was doing a lot of reading and thought of the Lunati over the current Purple Shaft I have now..

Below is the two sticks I was looking at.

I was cautioned by a friend that the Cams are sweet but not to buy the lifters as they
are made in China.?

Anyone here up on the lunati info etc....

My Dart has
340
purple shaft lift is .484
X heads
727
323 gear

thanks for any info
