Max lift with stock valve length?

Bewy said

The Comp 26918 Beehive will do nicely. Coil binds @ 1.100". Normally installed @ 1.800" with 125 lb seat. With your valve lift, you could reduce this to about 1.750" to increase the seat pressure to about 140. Beehives require less tension because of their lower weight & design.

Thats not enough spring load for even a mild solid roller.

200 on the seat would be the very MINIMUM ago use, especially with steel valves.

More roller lifters have died a quick death from too little spring load than too much.

That a slow idle speed. Or cranking the engine over with the ignition off to build oil pressure. That will kill a roller lifter right quick.
