Ok...This ought to stir the pot...

I agree that there are some who would contend your stuff is junk if you didn’t correct your geometry. But, I look at it as optimizing things. If correcting your geometry was free or a no cost process, took less calculations, who wouldn’t do it? In many cases I’m thinking there are those who are thrifty or miserly when it comes to doing or buying into some things? If it was free, cheap and easy to correct I bet it’d be a different story?
Without question I 100% agree that optimizing your valve train geometry is going to help. I myself opted away from some roller rockers I have to some 273 rockers because the rollers were trying to roll off the end of the valve stem. Now do I want to stack up offset shims or unbolt and disassemble my heads to have them machined? No not really for a daily driver. If it was a drag race effort and not just a bracket car that needed consistency I would be all over getting my geometry maximized...
You know as well as I do that if you don't do things or buy things according to the highly opinionated gurus out here that your stuff is junk. Of course it's only junk in the world of Internet... In the real world nobody calls your stuff junk...
