I have just removed one of my heads (289 HiPo) to investigate why my engine smokes and have found the problem. Only one of the valve stem seals on this head is in the correct position, the rest have come off the top of the valve guide tube and are floating up and down with the valve. These are white seals of some type of hard plastic (Teflon?) and have a coiled wire around the top section and a split band around the bottom.
My question is are these a press fit onto the valve guide tube or should they be glued into position. Also is this the best type to use or is there a better alternative?
