200 lbs might work on a small valve motor.

There's nothing in the rulebook that states you can't do lifter correction.

Before someone says that there's nothing in the rulebook that says you can, here are some things that are not in the rulebook that people are doing.

Using $1500 millimeter ring packs with spacers, some with lateral gas ports which are prohibited on pistons. Blending the valve job from the bottom cut of the seat to the top of the valve guide boss. Roller cam bearings. Bull-nosed cranks. Using clean PVC to pull vacuum in the crankcase. Oil shedding coatings. Trick ignition systems. Etc.

Here are a couple of things that people have been doing for a long time that are prohibited in the rule book. Porting heads and intakes and covering up. Modifying carburetors especially Holley's.

Let's not forget $6000 transmissions with aluminum everything and dozens of gear ratios. Trick rear ends with ceramic bearings, profiled ring gears and impact coatings.

Lifter correction is more in line with engine blueprinting than all of the above. I'm pretty sure people have been doing it, probably for a long time, especially on aftermarket blocks.
