Rocker valve assembly picture

[jcsb]

Doe's anyone have a picture of their rocker valve assy attached on their head? I am really interested in a shot showing the clearance between the bottom of the rocker shaft and the cylinder head nut at either end of the assembly. This is where there's a spring washer, spacer, and then the cotter pin.

This might help, scroll down through the pictures on Magnus' site, there's a couple of photos showing stock rocker assembles: https://healeyspecialists.com/work-in-progress/

I don't know if this is where is where you are heading but after I replaced my rocker shaft with a pre built one I had to grind off a fraction from the washer, rather than from the nut. I had changed back to standard studs and nuts from the waisted ?ARP type. Clearance is tight.

Thanks guys, I've seen what I need to do. The engine I'm doing is a complete rebuild with a new Denis Welch aluminum head, his studs, and his perches as shown. If you look there is interference between the bottom of the washer and the stud. Probably the perch is standing off .05-.075". Since the head is coming off again anyway I will machine down the stud to allow clearance.

Matthew,
Yes your right as mine was a combination of tolerances that have changed. I plan to take the offending studs to the shop and machine down the clearance needed. Thanks for the video.
