Switched to the Andrews EV 27 cam and at the same time went with the Adrews fully adjustable pushrods. So far the yseem to be doing fine. Do like the fact that it does not mean puling tanks and top part of head if I need to get into the valve train.
I have the Screaming Eagle push rods in my 99, and they have been doing just fine for the last 20,000 miles anyway. My valve train is very quiet but I am still running the stock cam.
When we were all riding Shovelheads and Ironheads we used to dream of hydraulic lifters that you didn't have to adjust....now we have them y'all wanna go back to the dark ages.
The ONLY advantage is that you can be lazy if swapping a cam or lifters but the potential problems caused by adjustable rods don't outweigh the tiny advantages in my opinion....I never use them....have fitted them for others, hated them, never again.
Thought when the heads were shaved you had to use adj pushrods.
