What Are You Doing To/With Your Car Today?
It looks like I may have been sold the wrong retainers years ago by the machinist who put my iron heads together... not only is the installed height way off (too low), but replacing a lock with a new Comp 613 makes it even lower. I think the dropped valve either spit out a keeper or pulled right through. You can see in the pics that the locks don't sit in the same place.
That's what I get for reusing parts... :realcrazy: New Comp 741 retainers on order! And a kit of shims in case any are too high once the right parts are on. Unless I want to pull the other head (and the right side is a royal PITA), I'll have to do the swap in the car. Oh well.
613 (no lash cap recess) lock, full spring load:
Lock as currently installed, with checking spring:
Lock as installed with full spring pressure. Sits even lower in the retainer...
