The heads are not installed. What it appears to me is the intake lobe is actually 287@.050, not 285. The change occurs at the intake opening point. It's 2 degrees earlier than the card calls out. This then moves the int C/L to 110.5. The exh open/close are at the correct 112 C/L giving a 111.25 LCA. It also appears the exh lobe is assemetrical rendering the measurement at max lift for C/L useless .
