I've been there too . When it happened to me a couple times I finally figured out I was sold the wrong inner spring . The inner springs themselves had 110 lbs of pressure . What is your seat pressure and open pressure ? Thats really the only way to find out why this is happening . I dont really think you need a roller there are alot of good solid flat tappet cams out there . If it is like the problem I had the inner springs and a new cam will cost a whole lot less than a roller setup . Bad thing is I'm sure your bearings are toast now they just dont like to have ground up cast iron run through them .
