I got my Nizpro valve springs put in by Nizpro. I supplied them with just the springs nothin else.. It may depend on how heavy duty your goin?

I presume your talking about valve guides or retainers... If so, dont need to be done.

On a lot of jap cars, these items are often replaced as part of a rebuild but I havent heard of anyone replacing these items with our vehicles...

This sound like the info your after or was it something else?

As far as I know, those that are building are using the stock retainers...

I could be wrong though so dont take my word as gospel. Hopefully someone that has built a barra engine can come along shortly and confirm / give further detail.

If I was you wilbaz, id be looking at a set of Nizpro valve springs too. Not sure if the crows are any cheaper but plenty of people are using Nizpro springs and are happy with them, they are also reasonable at around $300. Atomic also do some stronger ones again but they cost a little more I believe...

Most springs use the stock retainers, unless you have some head damage your retainers should be fine.

The atomic springs are rated a bit higher than the nizpro ones, however they do cost a little more

Well there ya go wilbaz - and Senna has built his engine so he will know what he's on about.

Again - Id probably go with the Nizpro ones over the crow's!

Good Luck!
