Aren't aftermarket roller camshafts considered competition componemts? (They sure are)
Aftermarket roller camshafts never had any kind of signifigant durabilaty.

They are heavy and require thicker pushrods and valve spring pressures.
They can also be pretty noisey.

The simplest way is the best way. Solid lifter camshaft.

It wouldn't be a bad idea to use titanium valves
either.

You just can't expect hydraulic lifters to perform well at those rpms. For one thing, you never get 100% lift because of the bleed down.
Rhodes lifters only help a little. They are just rapid bleed down lifters and give you a lot less lift at lower rpms.

With hydraulic lifters you are going to need more oil pressure, and spring pressure. How do you get more oil pressure to the lifters in a Cleveland when you are restricting oil to the lifters for bottom end durabilaty? As you heat up the oil and the pressure drops you get less lift.

I suppose if you ask ten different people about cams you will get ten different answers. Ultimately it is taste, sometimes experience. Bad experiences speak the loudest.
