Trying to decide between the following roller rockers

Lunati voodoo 1.6

scorpion, 1.6

trick flow 1.6

comp ultra gold 1.6

I have read tons of good things on the scorpions, and lunati's look beefy as hell, and the other two rate good as well.

Which one to order and why

Ugly?  Easy now -- that's my baby and it's got lots of unique character!  When I drop that built 445" stroker in it you won't have any time to "pull over to let me pass" because I'll have already blown past you when you figure out what the hell was that loud noise behind you . . .

I'm pretty sure that the Trick Flows are made by Scorpion. From what I've heard, they are very good rockers.

I've heard good and bad things about the Comp Ultra Golds, and I haven't heard much of anything about the Lunati rockers.

If you aren't in a hurry and are willing to spend a little more, I hear that the Crane Gold rockers will be available again in a couple months. They are literally the gold standard in aluminum rocker arms.

I had good luck with the Trick Flows, not so good with the Comp Gold. 

The Comp Cam Ultra Pro Magnums steel rockers worked out well for me.  Had a great lifetime warranty.

looks like scorpion will be the choice unless somebody comes up with great news about the lunatis (they just look so beefy)

Is it better to buy scorpions direct, or through someone like summit or jegs etc. Whats easier for the lifetime warranty?

I've got early Crane gold's that turn 9000 on my junk. Scorpion rockers are a POS as I've changed over 3 sets for friends who go only 6800 to 7000 with only 400 lbs on the tip +or- and they crack at the trunion.  Just my obseveration.

Unless something has changed, FR rockers were made by Crane. Except for the Cobra rockers, most were blue versions of Crane's Gold rockers. If that is still the case, they are excellent rockers.

I've got a friend with some from a 95 Cobra, what are those good for, 6000rpm or how much? He has no real plans for an engine soon, and I might end up using the heads myself for a short time.

Due to the 5/16" bolts and the diecast design, I'd probably limit the rpm and spring pressure. I've seen those rockers pushed in the upper 6000 rpm range, but I'd probably stop short of there.

And I'd try to stay under 150# of seat pressure. I know people that have ran more, but I'd play it a little safe.

Just a solid built 289 with well preped 351w heads and a healthy solid FT cam. The trick ( or most likely shit luck) is the short stroke and Crane tripple springs. I used to launch around 9000 and pull the handle around 7700-8200 depending on the day. The 6.00 gear with a 2.78 Liberty came on real fast! Remember, this was built in the mid 80's when all the trick shit we have today was unheard of for Ford's.

Engineer from Crane told me to keep lift under .500 on those also.
