I don't expect it to be a W2 head and really don't need it to be for my mainly street driven application. An OOTB W2 or with just some light work would provide the HP level I'm looking for at this point. The TF have a couple things going for them over the W2 even if the flow don't match up. Aluminum weight savings and potential to run a little higher compression on pump gas, standard rocker gear (hopefully), and standard intakes and header patterns. But, the W2 probably have more potential with a full porting job that would better support a stroker if I go that way down the line.
