80/90lbs seat pressure,240/260lbs nose(open)pressure will handle 8000rpm.sounds like to much pressure or not run in correctly or lack of lobe/lifter radius not right.

Did you use new lifters? Is it a new cam or a reground nissan cam? I know there are a lot of problems with the L-series valve train if you don't use the right parts together things wear out quickly due to the difference in the metals.

Guys,
Is there a rule of thumb for valve spring seat pressure and what would be considered the max for an engine that had a max. rpm of 8000rpm?
I'm trying to find some answers to a very worn out cam in a very short time frame.
Dave
