Those are the same pistons I have (except mine are .030 over), they have a 22cc dish. The D0VE heads are 75 - 77cc chambers, so your at the 10:1 compression range (depending on other build factors).
If the heads are stock now (un-ported) I would recommend you just get some aluminum TFS or AFR heads, which will save you a lot of weight. What you spend on machine work (studs, guides, larger valves, springs, etc. for the D0VEs) and porting will pay for a nice set of aftermarket heads. Unless you can do a lot of the work yourself.
