95 351 Windsor Help

[351Windsor]

I am starting a 351 Windsor project for a Fox Body. I have purchased a 351 Windsor out of a 95 Bronco. I have read that some of these models are roller ready and some have them already installed. How can I tell, or did this model only come in one style?

Pull the lower intake manifold off, it'll have a metal "spider" there that keeps the lifters in place if it's a roller motor, I don't recall which trucks did or didn't have roller motors off the top of my head though
