I am not a pro, but I have been told by several builders that the slot in the rocker arm mounting blocks are supposed to face up (the valve side). I noticed yours are on the push rod side. Did the CB instructions specify this? thanks
I keep hearing you need to get the bottom of the rear cup on the rocker and tip of the valve parallel with the machined surface on the head where your valve cover would go, then I’m hearing you need to get the face of the valve adjuster side parallel with the face of the valve, I don’t know who to listen to
Of course this is a lot of very confusing information in this poorly prepared video. Please let me know if this helps. I am not a professional engine builder but have a lot of engineering experience solving problems and developing manufacturing solutions. I would like to offer everyone a method I developed in 2015 and published instructions on The Samba. The objective in performing rocker arm geometry is to find the correct length push rod when at the point of TVL/2 by way of adjusting the shims under the rocker arm such that half height results in the valve stem plane being parallel to any other un-pushed stable valve stem. How is parallel determined? Most will employ the "eyeball" method as viewed from the rocker end but if small bubble levels are used then maximum precision and repeatability can be achieved. One bubble level is placed on any other valve stem with its adjuster screw removed. The other bubble level is affixed (magnet & double tape) to the valve lash adjuster screw. Once the two levels are approximately centered when at half of total valve lift then the push rod length can be measured. Centering the rocker arm contact with the valve stem at half height will minimize valve guide wear and resistance. Follow the path of the rocker contact across the valve stem surface to fully understand.
Real excellent build! Great attention to detail! i hope this engine runs for 500K mi!
I hope so too! Thank you!
Swivel feet adjusters; great call!
Das ist Gute!
Danke schön
Noice! 😎 STOC

I am not a pro either! Keep us posted if you find a real answer

Face of the rocker parallel to the tip of the valve, i posted a photo with lines showing this on the video
So far all good!
