I agree if stock pressure spring rule was left alone in 87 wouldn't need tool steel,ceramic lifters and everything that came after that,was just putting out there the effects of not having the spring pressure to control the valvetrain, if you want to run the aggressive lobes and crank up the RPM then you have to have the spring pressure.
The stockers I build have plenty of spring pressure,they make more runs and require less maintenance than my pure stocker with stock spring pressure does,there valves,guides,spings,valve jobs will last twice as many runs as my pure stocker does..
