A Close Look at Speedmaster's Roller Rockers
Hey all I haven’t seen much on this forum or anywhere else for that matter in detail on Speedmasters (Procomp) stainless steal roller rockers. So when I found a set on EBay for $165.00 with a set of measuring pushrods.

For that money I figured I’d bite the bullet and see if they are worth a crap.
You can go ahead bash these if want, they're not $800 rockers. I'm posting this if anyone is interested
Here’s what you get:
Notice it has the steel anchor plates instead of aluminum.
It's not show quality but the finish is not bad, and the adjusters fit tightly.
It has Bronze bushings.
the adjuster accepts a ball type push rod and there's a oil hole through the shaft.
I had a head lying around so I decided see how well they lined up, and right off the bat I noticed the anchor plates on the ends push the rockers too far in causing them to bind and become off center. But this is nothing a bit grinding on the plate wouldn't fix.
When I removed the anchor it lined up really nice, in fact the roller tip sits just slightly forward of the valve tip, so would think the geometry's not to bad.
Everything move nicely (even the roller tips) with not too much play. I think I'd replace the mounting stud with some grade 8 bolts, they look to be a bit sketchy!
From what I can tell (I'm no expert) these turned out to be better then I thought. With out have any experience using them I'd probably put them on a street motor. Hell there cheaper then what most people ask for 273 rockers.
