New rockers...

some home-brewed 1.6:1 rockers for our slant six...

We learned that they were originally case-hardened (had the Rockwell hardness checked,) so it was deemed necessary to anneal them for machining and welding. Now that they have been T.I.G.-welded, We will have to get them hardened again before they are used.

They're not very pretty, but ugly parts need love, too... Once the rocker arm cover is on, it doesn't matter, anyway... LOL!

We used a .110" 4" circular, metal-cutting, saw blade in a vertical mill (Bridgeport copy) to make the cut.

Geometrically, and, using our third-grade math skills, we decided on that .110" number to achieve a 1.6"1 ratio.

We haven't built a jig to check them for the actual ratio, but we will.

These rockers should increase the gross valve lift from .484" to .516" if things work out as they should, and we all know they hardly ever do...

Stay tuned...:happy1:

Sorry for the really poor-quality photos.... Best I could do...:angry3:
