I just got a set of CNC ported Patriot LS6 heads-bare. I also got a new set of stock GM valves with these heads. I bought them bare because I already had the springs. Now i'm thinking maybe I should just drop in a set of Manley SS valves in the stock diameter before I assemble them-but will these valves just drop in? The heads already have a 5 angle valve job. Thanks!

You can either have a machine shop do a valve job matching those valves to the heads, or take some valve grinding compound and lap them in. They'll probably be fine just lapping them yourself.
