rb25 Degreeing cams with hydraulic lifters?

[Desean Strickland]

How would i degree my cams on an rb25 hydraulic lifter head? lots of information online about degreeing cams on NEO or rb26 heads with solid lifters but cant find a definitive answer about hydraulic lifters. is the process just the same for both hydraulic and solid lifters on an rb (dial indicator on top of the lifter for measuring valve position) or do i have to mess with my lifter to make it solid for the degreeing process?

It’s the same as doing the others

You can lose information about timing at 50 thou, but the centrelines will still measure up correctly.

As per Kelford and other cam manufacturers, hydraulic lifters must never be used for degreeing cams. You will get false readings due to bleed down. 

You either need an aftermarket solid lifter or to modify an old hydraulic lifter for this task.

Alright well now I’m confused, some people saying yes and others saying no. How would I modify my hydraulic lifter? Iv already pulled them apart to clean them so I know how to do that but what would I change inside the lifter to make it solid? And how would that work with clearance between the lifter and the cam?
