- Tool steel lifter + EDM hole (assuming all the tool steel lifters have the EDM holes)

What I think I've heard between here and SpeedTalk is that tool steel lifters and nitrided cams are a bad combo. Now I'm wondering if tool steel lifters are simply a bad choice for long-term street use, even for non-nitrided cams.

What about standard EDM lifters and nitrided cams?


All I know is I used Tool steel lifters with EDM on a non treated cast iron cam, That is how Trend & Howards said to do it, for the money I wasted I could have gone roller to begin with.
