checking cam lobe taper/nitriding lobes

Pricing is based on pieces. So it’s cheaper if you do the cam and lifters together. I did the cam and lifters together and it was 150 bucks. Then, I didn’t use that cam and had to send the other cam in and that was $125.00 all by itself.
That's pretty reasonable. Besides increased durability are there any other benefits? Less friction and heat, possibly?
