Nevermind the last portion of my previous post, i figured out what to do with the vacuum lines... Im going to bypass the spark delay valve and the Normally open solenoid valve, and put a line straight from my advance can to the PVS valve. The PVS valve gets its vacuum frrom the intake manifold, and the carburator vacuum ports.

i read up on how the SPARK DELAY VALVE and NORMALLY OPEN SOLENOID VALVE work, and all they do is this:

NORMALLY OPEN SOLENOID VALVE- only allows vacuum to pass when transmission is in 3rd gear, It uses electricity to sense and close when the tranny is in 1st or 2nd gear.

SPARK DELAY VALVE- Slows down vacuum, it makes vacuum gradually increase instead of increasing at speeds unblocked.

Both those things were blocking my advance can, and are probably a big problem why my car lacked power in acceleration, hehe i just didnt see it coming because i could rev up in neutral and the timing would advance..... tricky technology i didnt know existed.... I SUGGEST WE ALL READ THE SHOP MANUALS!!!!! hehehehe...

The other end of the vacuum lines, with the EGR will just be gone.. no EGR on my new intake anyways... that port on my carb is already blocked anyways.

Oh the powers of reading!
