Unless you are going to do the guides yourself, go with what the shop is using, as long as the shop is CE or Ollies, or equivalent.

They all use good quality guides. If you are doing this yourself, buy from the host. Most any bronze guide will last longer than the rest of the engine. But if you are doing your own, you should research this some more, a lot more. How do you intend to makd sure the guide is the correct size after installation? See a previous post on guides by me. Valve guide tools, K- line Tools. The company offers a complete line of valve guide tools and includes a lot of good info on guides. As to guides they can be obtained directly from mfg if you learn what is needed. Will save you some bucks if you invest the time to learn about them. Otherwise buy from host or similar source, they only sell good stuff.

Do not take any info on whats best from any web site or forum. Use mfg literature, tech articles, and shop recommendations for guide. Most of the rest of the stuff, like this can be second hand.
