I've been "researching" hyd roller lifters for my 451  build and came across a few posts over on Mopars about avoiding Comp cams hyd roller lifters as they stick. These scorpion lifters were recomended and owners seem to like them?
Anyone on here know anything about them? Made in the USA I see ! 
In this post it says Jonhnson lifters were bought out by scorpion?  Johnson seemed to enjoy a good repuatation?

Johnson has about the best reputation in the industry for lifters , never heard of Scorpion .
any hyd lifter will collapse with serious spring pressure limiting the cam profile , still trying to use a non adjustable set up huh !!

hyd roller lifters have been in use since the '90s on OEM cars.  4.6L Fords, 5.7L Chevies and LS cars, and Mopar Magnum V8.

For a street car, you can't go wrong and you can get more aggressive on the profiles than a non-roller.

I say go for it.  Worth the price.

   Ya still can't decide...
I have 4 people that I really value their opinions/experiance ( you being one of them) that all tell me different ways to go. ... well 2 say go hyd roller, one says solid roller and one says solid flat tappet.
My head is spinning!  No matter what I decide "someone" is gonna say " I told you so/ shoulda went with what I said...!"
So I'm just researching my options at the moment. Still awhile till I need parts, camshaft wise , so I'm just "weighing " my options.
Building a machining fixture at the moment to drill the hole for the valves in the stage 6 heads.....

I was going through the same debate...

While the performance and lack of maintanence of the hydraulic rollers drew me in too, my engine builder talked me out of it.  We ended up choosing on a solid flat tappet lifter with an EDM hole in the center for improved cam lobe oiling (primarily during break-in).

PS  My engine has just been finished being built, they should be dynoing it with a carb then my EFI system in the near future.

Hyd roller will work fine , you will leave some power & RPM behind
 Solid roller is good too but you will double the cost + you have extra maintinence with the broze dist/ oil pump drive that will need to be replaced regularly .
With any Roller cam you need a bronze tip fuel pump pushrod or it will eat the cam
