sorry bud, you cant do that. You will need retro fit lifters or a retrofit-smaller-base-circle camshaft. Both are price. For what you pay for the retro lifters, you can pick up a used roller shortblock!
Crane cams has some retro-fit roller lifters. They require head removal for install, BUT they all use of any standard circle cam. fordmuscle.com has an article about they (subscription required.)
They have a price, but if you're wanting a roller cam shaft (and I wish I had gone that route...) they are simpler IMO.
