all in a nicely packed box


one cylinder set up


rocker has a polymatrix bearing. no needle bearings means less friction loss.


Rocker stud towers had to be cut down .170" to fit the shaft mount. the holes had to be drilled and tapped to 3/8-16 thread pitch.


You can see where the valve cover wall had to be notched as well to clear the rocker. Also, on the right, you can see where the bolt boss had to be machined down.


stands on head


rockers installed


some close ups of the rockers. will need the 3/4" spacers to raise the valve covers enough to clear.

When do you expect the dyno results? Kinda wanted to see someone do a recent test of these...I know Tony Mamo has tested them with good results, but not much is ever said about them.

i won't have any before/after test myself, as i'm putting these on a completely different motor. vinci has already done some testing on their C6 R&D car. they tested them against the 1.8 quick lift rockers and made 19 rwhp more with the 1.7 shafts.

I see...that's really what I was hoping for - additional results. How much would you estimate the head machining would cost on average? Doesn't seem like it would be too hard, but I've never had someone do machine work on my heads.

it cost me $200.00 just for the machine work to get the rockers to fit. with a complete valve job, it was $400.00

Not bad at all...and they are a good price for a shaft mount system to boot. I'll have to keep these in mind when I get squirley with my engine...
