Most likely stage VI heads.

Nice.

You can measure the lift with a dial indicator off the lifter. Heads are hard to tell until off apart on the bench. I would think that valves, seats, and guides most likely will be needed. Mag first to make sure there are no cracks.

For one I do not ever remember seeing valve stem heights that bad. Two you obviously have cylinder leakage. Three it will never be right in the condition it is in. Myself I would do the leakdown test. If its valves then I would pull the heads. I would then measure the cam lift to get an ides of...

Your heads are messed up. They need to come off and be rebuilt or replaced.

Just google 69 gtx heater box rebuild.

Big block trucks had them. but 78 was the last year. Lots of 3/4 ton used them and I think up to 93 will fit. The master might have to be changed also depending on yow it bolts to the booster

Valve cover will not come off with a big block and that booster. The booster is the wrong one for a big block. You would need the smaller diameter tandem booster.

Just that they are opening and closing the valves correctly.

You can. Then with the covers off just crank it for a while and watch every rocker. If it all looks ok put the covers on and run it.

Someone was trying to correct the valve train geometry.

Run a leak down test. You could also pull the valve covers and inspect the valve train. If compression was ok I would be looking at the cap as 3 and 6 are next to each other.

If you are sure that both halves of the master have let all the air out you should of bled it ok. On the car or bench will not matter as long as you fully stroked the master to get all air out. You might be on the right track that the master has failed and needs replacement. Get a new master and...

Did you actually bleed the master with tubes going back into the fluid? Did you verify the caliper bleeders are on top? Did you make sure the rear shoes are properly adjusted? You ask questions but give no answers.

The booster is just an assist. You should still have brake pedal.

Did you bench bleed the master. Are your front bleeders on the top? Are the rears adjusted?

I see that now. Guys make the newer fit the older by methods I would not use. Looks like they may work but you have to use the newer control arms. Check with @mobileparts to see what he can supply.

Why wont it work?

What about the rotors? Better add the numbers up.

I am not big into C bodies. But I would think 74-78 C body stuff would work and is available. You might need the knuckle/spindle also.
