Aluminum cylinder heads
I was explaining how I set up the valvetrain.. See where I mentioned spacing the rockers and centering them on the the tip of the valve?. And yes I mentioned how I measured for proper pushrod length.. But all this aside, what's your point?
My point is, I haven't ground on a rocker arm in at least 15 years, including the PRW stainless rockers. I have used dozens of sets on in-house builds, and sold many more sets to customers without issue, including on E-street heads. Why? Because, as was mentioned previously, correcting geometry eliminates symptoms of poor geometry, such as fitment interference, or excessive sweep. Just because the rocker does or doesn't clear the parts around it is not an indicator of whether the rocker is good or bad.
Frankly, the Harland Sharp and Mancini rockers you are promoting are some of the worst when it comes to its design engineering. I've made corrections to many sets for customers, but haven't used them, or any copies of them, for quite a few years. There are better choices for the money.
In summary, you say there was something wrong with the rockers, and I say there was something wrong with the stand location in the cylinder head, regardless of the roller rocker arms used. Imagine having the benefits mentioned in the tech articles, if the shafts had been relocated.
