Long valves on W2's with .600 lift?

A real shop
Even on the big monitor that's hard to read
notice 1.7x1.6 rockers
tiny base circle must be a stroker
tough to make those work due to side loading
but one way tofake an inverse radius without actually doing it
notice the lobe separation of 103
I checked- that's half way between IO27 and IC 53 @.050
I can remember using that secret on SBC 30-40 years ago- necessary due to stroke and rod
but see the not that if timing off the intake lobe top icl to use a 101 ICL
shows the asymmetrical nature of the lobe
and why many get screwed up and install their cams retarded by timing off the tip icl
WE have what we have with no roller cam rule and .904 lifter

Isky has no beehive spring suggestion
suggested a spring with about 186 on the seat
must have talked with the wrong guy
I'll go see Ron when back in LA

Evidently they run springs closer to coil bind than I ever did
so selection is important which sets the stem length and groove location
maybe that big tall spring may or may not be the right solution
did you say 5/16 8mm 7mm exactly what are these valves
from what I hear the light weight is nice even at your target rpm
big item missing is off the corner rpm
I'm thinking corner to flagstand is what is going
to move up in the finish results
so
valve stems
rpm off the corner
bead or square locks
gas or alky
I'd let jones pick the springs
It's like blending snake oil
