I think I still have some gasket paper here that is for the intake gaskets it is a special gasket material

When you're frustrated, best to take a breather or switch to another task.
I switched gears to the brakes and made some progress...

First I upgraded the Corvette Master Cylinder to a Chrome finish version:


After it was bench bled I redid the lines to the Wilwood unit with aluminum:


My EBC red stuff pads arrived a while ago that I chose for the low dust compound:


I finshed up the rears with the cross drilled rotors and Russell stainless flex lines:


These are C5 Corvette calipers, pads and rotors:


For the C4 Corvette front brakes, I had a problem of the rotors not fitting between the pads!


I thought maybe the piston in the caliper didn't retract all the way but the other side had the same issue.
It's weird because the EBC 84-87 Corvette part number is correct and they fit otherwise.
I checked the stock Corvette vented rotor thickness specs and new rotors are 0.79" while minimum spec is 0.72" and my used ones are 0.77".
So buying new rotors won't solve the problem either.
It doesn't make sense machining new pads and no one locally had OEM pad in stock to compare pad thickness.
Any suggestions how to solve this?

GM also has their own silicone. It's a little pricey but works great.

there are 2 diferent sets of pads for the 84 to 87 corvette the pabs you have there are for the heavy duty brakes not the standard duty brakes there is a big difference is pad thickness between the sets get the standard duty pads and they will fit other wise you will need to get these shaved to fit

Well two parts store couldn't figure out what was wrong with the pads when I brought them in with the calipers and rotors.
Turns out I had the inboard and outboard pads reversed.
All I could do was laugh at myself since this is really the easiest possible solution.
I also learned avoid to asking technical questions at parts stores that have unknowledgable seniors, kids and women working at them.

Joe, here are the stainless lines installed - they fit great and look like a nice upgrade to me

I would be concerned that too much braided stainless in the system (as opposed to hard tubing) is going to compromise pedal feel.

Unbelievable. Just spent almost the whole day going through this thread. My body hurts just from reading all this, I can only imagine the pain of building it. How many years? Hours? Dollars? Amazing, my hat is off to you both, along with my shirt, shorts and rhinestone studded thong.

The four rubber flex hoses were replaced with stainless which should give a firmer pedal.
The other two pieces are 9 inches long so I don't expect to feel a difference.
I bled the brakes on the weekend - took a while to get ALL the air out of the new hard lines.
I'll post how the brake road test goes will these pads, stainless flex hoses and the adjustable proportioning valve.
