Depending on how high the compression is , you might need to use a copper head gasket !
Yes - a 57 x 55.5 (140) engine should rev out harder than a 55 x 59 (140) motor ! Long stroke engines pull great from bottom end to midrange but then they tend to drop off quickly up top . You'd need to run a bigger cam in a 59 stroked motor to get it to rev !
