A cheap thing you can do is to install umbrella seals over the valve stems, under the springs. This keeps most of the oil from going down the guides. I've did this and it does work. It's not the right way, but it will help for a while.....Other wise, just find a better set of heads. You'd have to take them off anyway to reem the guides.
