Rocker guide rail off again as tappets baggy on 6,7,8 - after 1500 miles - valve stem caps well beaten in that time, so kept looking. Slider tops look OK, valve springs OK, rocker surfaces show no wear, pushrods all true and not worn. So unless anyone has any other ideas its head off time...

Thanks for tips so far. Just to be clear rocker guide sheared before any tappet work done, will check cam followers and definately check sliders to see if they have rotated, fun day tomorrow, might fit a rocker cover zip, save on instant gasket. Rocker contact areas show no wear. Allen
