When flowing the heads the retainer was touching the valve seal @ .550 lift. Is a voodoo .513/.533 to close for comfort, or does anyone know if this cam really grosses .533 or less lift on the exhaust side?
. The stock rocker arms are actually a little less than a true 1.5 ratio and I'd say you have just enough room for the .533 to clear if it wasn't hitting it until the lift reached .550. With proper valve springs I'd say you're good to go
