I've been contemplating my next engine upgrade for the Ranger's 289, and am thinkin that I'd like to get a set of 1.7 ratio rockers to get a little more lift out of the cam, and airflow out of the heads, without opening up the engine. I've already been told by a lot of the guys here that the Scorpion rockers are great, but I was looking around on eBay to see what's out there and came across this rail mount rocker setup:

(this is 1.6 ratio, but there was a 1.7 ratio set a couple days ago)

Judging by the price, I'm guessing they're made by some no-name brand like Pro Comp, so the quality could be questionable. But on the other hand, you can't deny the advantages of rail style rockers on high rpm engines (which I think my 289 qualifies as). So, what would you guys go for if you were in my shoes? the generic rail rockers, or the good-name roller rockers?

And along the same lines, what are the odds that I would need different length pushrods swapping to a different brand and ratio of rockers? Would the rail type be more likely to need a different pushrod length? I'd like to avoid having to change pushrods (cost savings, of course).
