So best bet is using 8.5:1 pistons and a VE head to get 9.3:1 ? Am I right in thinking this or am I missing something somewhere ?



yes, if they are for a DE or DET, if they are for a VE the compression will not change...IE if you swap a VE head onto a stock DE or DET block you will get (de 9.5:1+.8=10.3:1) (det 8.5:1+.8=9.3:1) or if you are using de/det pistons add .8 to the CR of the pistons. VE's will remain the same
