[TR] TR3A Rocker arm "spacers"?

Instead of springs?

Hoping to reduce some fairly bad valve gear clatter this winter so when I saw
the following ebay item I was intrigued.
Whats the conventional wisdom, are they better/easier/quieter then the OEM
type
springs?

Some back story as well:

Valve gear was a bit noisy and while adjusting the rockers I noticed that one
of the
push rods was dancing a bit because
it was bent, so I ordered 8 new ones.  Put them in, readjusted the clearance
and it
didn't really do much for the noise.
  3,000miles later and it was a LOT noisier, figured maybe my adjustment
slipped.

Re-adjusted again (didn't find any slippage) and valves were silent and smooth
like
the finest swiss watch, for about 5
minutes.  Reved the engine a few times and the noise level built back up to
normal.
I'm thinking maybe there's play in
the rocker shaft & bushings so I thought I'd replace the bushings over the
winter.

And maybe now the springs for spacers....?
