When you order RLB-CDPB25, RLB-CDPV25, or RLB-CDPW25 you will receive a basic long block as per assembly shown in picture (note valve covers are not powder coated unless you specifically request them as such for small additional charge). If you want the long block fully dressed and timed you must order the appropriate fully dressed package at the same time. For RLB-CDPW25 you should order D-AVCS fully dressed package and for B25 and V25 versions please order S-AVCS fully dressed package. The fully dressed package is only the parts and labor for the additional parts to dress and time the long block.
