I've made switch to a solid roller, but am still curious about what combination of cam treatment & solid lifter material is getting the up for street & strip use these days.
- Standard cast iron cam core
- Standard cast iron cam core + nitriding
- Standard lifter + EDM hole
- 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?
