I get it but you guys are throwing around some big blanket statements based on personal bias. The people with experience know what you mean but those that don’t are taking it at face value.
I'm not making blanket statements. I'm relating facts from doing this **** for a long time and learning the hard way. It's not a bias at all. Like I said, I was on the HR bandwagon like jack the bear. Then, as always happens the lobes get more aggressive so you need more spring load. More spring load is now needed. The hydraulics HATE that. So now, you need stiffer pushrods because instead of running a 30 grade oil you need a 50 grade oil. Now, you have to adjust the clearances to compensate for that heavy oil. Then, the lifter manufacturer will swear on a stack of Bibles that you are the ONLY GUY IN THE COUNTRY who thinks you need that heavy oil. The ONLY one. In fact, their super trick lifters are designed to use much lower grade oils because they use new CNC manufacturing methods to keep internal clearances pussy good.
The only problem is you can't give up that much hydraulic load (only way I can think of right now to explain it) to keep the valve train stable at RPM.
That's when you say piss on this and drop in some solid rollers and be done with it. You can now run 240 on the seat and 600ish over the nose and everything is as happy as a pig in ****.
