I've been thinking about this project for awhile and have done some homework. I pulled off my cam cover last week and looked at the outer tensioner which was already about half gone at only 20,000 miles. The inner one looked good but was hard to tell without taking it apart. I'm still not sure whether I want to simply replace with the old style spring tensioners (cheap) or upgrade to hydraulic (expensive). Regardless of which one I do I will still need a cam service kit with all the gaskets. I also plan on replacing the inner bearings, so Glazier if that inner bearing remover/installer is still available I am interested. I already have all the other tools I need including the oil pump pins, and cam locking tool.
I know the screamin plate is only the beginning of the cost. I figure if I upgrade I'm looking at $500-600 with the cost of gaskets and spacer kit. However, I plan on removing the rocker boxes to remove the standard pushrods so I dont have to buy adjustables. I've done rocker boxes before and it's not that hard.
