* Note : These Pan/Shovel valve springs
are not bolt-in items. Always make sure to check the minimum spring spacing
and to keep a minimum of .060" before coil bind, at full lift.
Early 1948-1980 heads must be machined to accept AV&V's late style lower collars.
You may need to machine the spring seat
with Goodson spring seat cutter #VSS-1680HD and/or use AV&V upper spring
collar kit #R530-4 and/or machine the valve seats deeper to get the
correct spring spacing.
For reference, on late style Shovel
(1980-1984), with a 1.630" valve stem protrusion, the spring spacing is
+/- 1.375". |
