Correct spring compressor for valve-stem seal replacement?

[KDMatt]

Hey everyone! it's been several years since I was last an active participant of this community, so forgive me if things have changed!

I've had my Z for almost 11 years, and once upon a time there was a great, definitive procedure for changing the valve-stem seals. I'm wondering, first, if that's archived anywhere (since the original was on Geocities and I can't really find it anywhere now.)

Second, what is the tool people are using for this job these days? Back in the day, the tool folks swore by was KD Tools #3087, which was supplanted by a Jet tool #H3349. I can't find either of these anymore, and I'm wondering if anyone has any experience with this one: http://www.amazon.com/Neiko-Spring-Compressor-Universal-Overhead/dp/B009GLIOSE/ref=sr_1_20?s=automotive&ie=UTF8&qid=1461721775&sr=1-20&keywords=valve+spring+compressor

It looks to share a lot of the same design qualities as the KD Tools one, but uses its own bar instead of hooking around the cam. Has anyone ever used one of these on a Z, or would I need to be a guinea pig?

Thanks in advance! It's good to be back!

The first one you showed is designed to have the cam and cam towers removed.
