Power to Manual brakes on 72 c-10

[I_Wanna_Go_Fast]

Hey guys
First off, my apologies as I know this has been beat to death on here. I did a ton of searching to find a lot of good info, a lot of bad info, and a lot of conflicting info.
I was hoping to ask the experts the reside across this forum for some definite answers on converting my 1972 c-10 from power brakes to manual brakes.
No need to bring out the torches and pitchforks, I know I will get a lot of "But why...?" for this. You see, this is a street/strip truck. 540 BBC, I am having issues removing valve covers to adjust lash. Took the factory brake booter set up out when the 540 went in, bought the master cylinder/smaller brake booster set up from Jegs to help out with my problems ( https://www.jegs.com/i/JEGS/555/631442/10002/-1 ) helped slightly but not a sustainable solution.
Trying to adjust valve lash is still a PITA on the drivers side. I would like to convert to manual brakes to free up some space as well as clean up under the hood. I know the master cylinder is good for power or manual brakes but unsure of what proportioning valve to order. Any help is greatly appreciated.


Sorry for the novel..

Prop valves are disc/drum or drum/drum for these trucks. Disc/disc are available through the aftermarket.

The combination valve should be the same whether power or manual. Remove the power booster and get a manual brake pushrod and manual brake master cylinder. The manual MC has a deeper hole in the back to keep the pushrod from falling out, aftermarket ones sometimes come with a spacer to put in the back or have one that can be removed.

I got a aluminum master off a 84 c10 w manual brakes for my 73 stops fine.

Didn't touch the prop valve
