How long is chatter noticeable after start-up in your car? Did changing to a high quality synthetic make a significant difference?

The car has 10k miles and has always had some minor chatter at start-up, but less apparent with a good synthetic. After about a minute or two it's silky smooth.

There are no lifters or cam buckets, the cam rides on top of the rocker, and the rocker opens the valve.
Like all "solid" cam engines, some noise will be heard from the direct contact between the rocker and valve tip.
