The 85 block will not accept an OEM roller cam. Two reasons:First flat tappet cam lifters are ground to keep the cam pushed toward the rear of the block. Roller has a cam retainer plate that does this. Nose of a roller cam is stepped to fit the plate. Second the roller lifters are held in position by retainers and a hold down piece called a spider.Keeps them from rotating as the cam turns. Several cam companies make a retro-fit cam/lifter kits for non roller blocks but they are very pricey.
