I've run roller rockers since 1993 in my 6. At the VTR National Convention
in Seattle that year, I met a guy named Richard Good who had started a side
business in auto parts for 6's. He had a set of his new roller rockers with
him at the event and our friendship started when I made this purchase. I
couldn't wait to get back to Texas to try them out. The rocker arms are the
1:1.65 ratio and I couldn't be happier with their performance. It was like
putting a mild higher lift cam in the car. As you guys know rolling across
the top of the valve stem, opens the valve a little more. There is no wear
that I have noticed, but I don't drive the car that often. Since '93 only
25K miles, (after my rebuild at 100K), has been on break-in road trips and a
few times a year my wife and I autocross it. The boost in performance was
immediate and noticeable. They are easy to adjust. There is no downside
that I know of. On a milled head you have to watch the geometry of the set
up, just as you do / should with any installation of valve train equipment.
I had to make spacers under the rocker shaft chairs, but that was because I
milled the head a tad. I also had to adjust the spacing along the shaft
with washers to center them on the stems. I'm sure Richard has now made
these adjustments in the sets he now sells. I have also run my stock push
rods since installation. I told Richard recently that I have almost every
thing he makes, and that he should start a new expanded catalog.

Peter!
This is a great question. I have heard so many stories that I dont know what
to believe. It will be an interesting thread and very informative.
I am all ears.
Just what are the benefits?
What are the downsides?
What are the pitfalls?
