Default Merc 900 valve Springs and lifters
Anyone know who made the springs and lifters for 900's ? Want to source everything before we pull it apart.

Which comp springs? I only did a quick search but couldn't find any comps similar to the recommended crane spring #99876.

160 closed @ 1.968
468 open @ 1.348

Seems pretty light pressures for that cam but it's what the card shows.
