Pull the valve cover and use a small flashlight to check for dog bones on the lifters. If you see them it's a roller cam.

No dog bones.

A "spider" was used.

Bolted to the gallery floor..

You are both correct:

The spider is used to keep the dog bones in location. Each leg of the spider goes to the center of the dog bone...

Dog bones and spider = roller cam....
