Anyone used these before and have any idea how much needs to be cut to get them to fit?

I haven't used them but shouldn't your machine shop know? The one I use has tons of books with numbers and measurements of every nook and cranny of every block and head, ever.

ya thats what i thought as well, they called me today and told me they dont fit so i talk to ConceptZ cause i thought maybe they sent me Z33 guides but they use the same guides as Z32 so im sure they are the right ones. I will have to have a talk with the machinist tomorrow
