What is the benefit of something like this? I am about to begin re-assembly on my mild-build 318. So, if something like this is recommended, now would be the time to pick one up and install it.

That thread pretty much covers it, kinda for hi/Po engines, hi rpm, hi spring rates.
It's a good read, especially for race engines.
