i'm curious as to what bad you have heard about namura.....are they machined out of spec, crack, teflon separation? i know many just call them junk because they are not wiseco, or have an asian sounding name. pro-x is just a factory replacement that cost less. the better ones i mentioned are made from better alloys and are improvements in strength, reliability, and performance.
the namura complete kit is 145, btw.
