Crower 68404 springs will install with stock retainers and allow lifts up to around .540" (double check me on that). Of course, if you swap everything from the 62s then no worries.
I would run a modern cam profile with a tighter lobe separation than the 068. The 068 is pretty mild and is really designed for high compression engines. It works well in 455s with low compression but it will have a soggy bottom in a 400. I like Squidward's rec. for the Lunati. Also, the Summit 2801 would be a good budget choice.

OK, a more modern cam sounds like the way to go. |

Why not use a set of Rhoads lifters ? It will keep things mild until you stomp on it, then they bring the cam to its potential.

I was thinking Rhodes might be an option but not sure about the noise level. I do have Crane's version- High Intensity that date to around 87, they are NOS but haven't read much about how well they perform. It would save me the hassle of ripping the front of the engine off. Never considered using them with the 62's as I am sure denotation would be worse.
