Has anyone tried Dart pro 1 cylinder heads made for 525s yet? CP says gain 75hp with there stage 3 kit. Heads, Modded throttle body, ecm tuning. Was hoping to hear some real world numbers or mph gains with this setup....

Not sure how available these heads are. Things may have changed by now but we had two sets of the them on order for a couple months last year for a pair of big bore 525's we built. With no estimated arrival date we were forced to stick with the stock 525 heads.
