...The hard way.
Unfortunately, I tend to be a bit complusive when it comes to buying new and "improved" parts for my TR4 as evidenced by the last topic I posted, "1.65 roller rocker dilemma".
For what it's worth, I did learn a lesson here. Of course it was an expensive lesson, but I felt as though I should pass on what I discovered just in case anyone else may be considering the same route.
It doesn't work. Forget about it and don't waste your money.
If I'm wrong and there is a simple solution, please don't tell me, it is too late and where the heck were you in my last topic...lol.
For the 1.65 ratio rocker arms to work, the distance between the centerline of the rocker shaft opening on the arm and the adjustment screw at rear must be decreased. No way around it. What this ends up doing is pulling your push rods closer to the rocker shaft, in turn, placing them on an angle and in my case, actually rubbing the wall of the push rod tube. If your head is off and you have the tubes enlarged, I suppose it may work a little better, but your push rods will still be at an angle. So for what it's worth, in my case about 700 bucks, take my advice and forget about it.
The problem, as I see it is caused by the location of the stud the rocker pedestal slides over. The stud is too close to the rocker shaft and the only way to offset this is to push the the pedestal closer to the puh rod tube, which in turn places the stud inside of the rocker shaft opening on the rocker arm. I suppose that something could most likely be engineered to make this work, but trust me, there is no simple solution. At least none I could find.
