This will pretty much give you an idea of what manley developed in 1990s that is sort of what I was doing in the 1970s

the cutaway profile drawing shows visually how the lash cap cap be set up to rest on the keepers so that the spring pressure is directly against the rocker tipand the valve stem is in tension at off the seat duration of the cam lobe

Pretty interesting stuff. I'v never seen anything like that - but my experiances is pretty limted.

Two statements in the catalog cought my attention: "Clearance in the system allows linear valve lock movement independant of LocCap". That (to me) means that the bead lock is for retention only, and doesn't transfer the force to the locks. I can also see where it could do both. IDK.

Also, "100% contact between the underside of LocCap and valve tip." If it's in 100% contact, how does it not transfer pressure from the rocker tip to the valve tip? Again, IDK.

As I read the catalog page, it appears to be a lash cap with a positive retention system. When I look at lash caps, I see the thinnest ones are 0.040" How thick are the LocCaps? Do you need to lengthen the push rods to compensate? I wouldn't think .040" would make that much of a differance in my application.

The more I learn about Lash Caps, the more I think I like the idea.
