I ran an HEV in a small block years ago.

1st cam wiped out in 200 miles. Although I insisted we used the correct pressure springs, they told me the reason it wiped a lobe was because I hadn't purchased the springs from them.

After I dug all of the metal out of the pistons, I built another motor and had a 2nd cam wipe out in about 1500 miles. Although I had used their cam, lifter, and spring combo... they told me my block had poor lifter bore geometry, and would not cover any costs of the repair.

Then I bought new pistons, new bearings, rings, etc...bored the motor .010" over, BUSHED the lifter bores as instructed, and broke the motor in on the dyno with the outer springs only as instructed. It wiped out ANOTHER cam of the same HEV profile.

I'll let you decide if you want to buy or use anything from them...but I put a roller in it, and never looked back.

You don't need a killer attack roller lifter profile. Every production car on the planet has a roller cam in it...so the durability is fine if you use the right parts.
