Long valves on W2's with .600 lift?

junkyjimmy
we hope to have some low cost fun

current valves are Manley Pro flow 3/8 stem which are at 1.95 spring height
heads are cut for 1.5 inch springs (heavy tripples)
We need to come up with springs 1.95 minus spring seat beehives would be much lighter
new proposed intake is a .200 long chevy valve which is same length saves some weight
similar to the valves I used to run
Plan was to go with x nascar Ti valves at taller installed height
but require to be cut for bead locks
and would require reshimming the T&D rockers
so not this year
need a 11/32 or 5/16 1.6 ex 2.150 long
