.050" lift numbers can be misleading depending on the ramp design and total lift.

It's nice to know what the zero lift numbers are, especially with 4 valve, which have fairly low lift numbers.

You'd still have to verify piston clearance if you kept the LSA, but it should keep you from having to cut your pistons.

Cams are kind of a black art with diesels. Few back-to-back tests have been done. Turbo engines aren't as reliant on cam duration as NA engines, in fact too much cam hurts performance way before it does with NA.

I think a "bit" more duration would help high RPM operation, but how much a "bit" is, I don't know.
