CB 1.4 R/R oil squirters

So I am in the process of building my 2058 type 1 and I'm doing some of the hvx mods to the engine. One problem I see with the CB 1.4 ratio rockers is no oil path dedicated to the lash cap or valve stem with the exception of splash oiling. I've been toying with a few ideas to solve this, one would be an oil spray bar, notching the side of the rocker arm where the shims go(idea being oil will follow the path of least resistance and aim the notch to the rocker tip area) or drill a small hole under the rocker tip( on the rocker shaft area) aimed at the valve tip. I want this thing to last so I'd like to get some oil up to the valve tip area without compromising any structural integrity. Any ideas

I did what you are suggesting, with a notch ground into the thrust face, aiming for the lash cap.
So far so good, but, mine are Autocraft rollers.
Your plain shaft setup might want the pressure..

If I was to do it again, I would drill a tiny hole to aim the spray at the lash cap.

The pushrods on a type 1 aren't square to the rocker shaft,
So it seems the thrust needs the oil it can get.

Best to do all of your Hoover mods at the bottom end to get enough oil as well IMHO.

Really good idea..
Let us know how it works out!

Another member suggested drilling a small hole in the pushrod, which should work like a sprinkler. It wouldn't be direct but it would definitely be better than nothing. poop I might just do both:) a couple tiny holes should still be an acceptable amount of oil loss nothing compared to worn out main bearings. The bottom end hvx mods have been done still have to do the rocker shafts and I would think as long as the tiny hole in the rocker is properly chamfered it shouldn't lead to breakage
