Performance timing

AJ/FormS

I have a push on chrome breather on the passenger side valve cover and a pcv valve on the drivers side. Do i need to get rid of the pcv and put on another push on breather? Also my 727 has a stock torque converter . My truck has power brakes. Do you think ill have to drill those holes on thebutter flies on the 600 eddie i have on the engine? If i remember after i put 500 miles on the new 318 i did a compression test with it warmed up and plugs out coil wire disconnected and 4 barrel wide open and i think it was 130 psi per cylinder . I let it crank 4-6 times each cylinder
