I believe there is a member here with either SR's or EZ's on a 572. Maybe Ron (firefighter) can chime in.



Mine has a set of the 295 cnc EZ's @ 10.7:1 in a 572ci street/strip build. Makes Killer torque (720 ftlbs)and descent horsepower (720HP) that is all in by 6000 rpm. Heads flow almost identical to yours. On a 540 the tq peak and HP peak would be higher but not by a huge amount. I'm running a .660 lift solid roller 266/272@.050 on a 110 LSA.
