Here is how Ted and I solved the problem on the 2018 303Y for EMC. Iron head rule, 1.6 Harland Sharp roller rocker arms, Smith Brothers push rods, etc. Joe-JDC

Here's a link to Ted's article ... There 'ya go. Just like PREGO, it's in there.

“The High Side” (?). Does that that mean longer valve stems, or longer pushrods? (sorry if I’m a bit slow on the uptake). That means to err on the side of having the stand positioned slightly higher than ideal. Right. I was confusing ‘rocker’ geometry with ‘adjuster-ball/PR-cup’ geometry. Mostly a wear, rather than performance issue (?).

Rocker geometry is both a wear issue and performance issue. Poor geometry increases wear and decreases lift.

Funny how the mind plays tricks. My comment was based on a memory re: a (supposed) tech article from years back that dealt with increased adj. ball/cup wear due to setting the adjuster/PR length for max. rocker ratio, but a thorough search of all my accumulated literature proved fruitless. So, must be a figment of my imagination. Search did point out though how complicated are the complex myriad of factors involved re: the compromises between perfect geometry/min. wear, and power range (as Ted’s single comment re: sacrificing guide wear demonstrates).
BTW: Re: the OP’s original question: I noticed a tech comment (while searching) that stated increasing cam lift typically requires milling (not shimming) the stands (likely in relation to otherwise OEM setup).
