In the continuing refurbishment of a 455 we have examined the lifters and valve train and found Crane High Intensity lifters part number 99384. The engine has a Crane cam meant to emulate a w-30 spec engine. We surmise the lifters were used to increase low rpm vacuum to enable power brakes. Are there any tricks of the trade we should know about to adjust the to rocker arms to accommodate the high intensity lifters. I realize this sounds like a rookie question but that's what I am. A rookie. We had the heads off and replaced the valve guides and are now in the reassembly mode thus this question.

Those or any Rhodes lifters set the same basically as factory hydraulic.
