After hearing of the cam lobe failures, with higher pressure springs, it seems like it might cure that. You could also do it with solid lifters, by drilling a side hole, to meet the cam lobe face hole.

They would be easy to drill, with a 1/8" solid, carbide drill. 3/32" would be a a little harder to do and if you go smaller than that, you'd have to do it with EDM.

Just a thought, I'd be supersized if it hadn't been tried at some point.
