                Any Red pollution valley cover will fit OK. Blue will not.
 I'm running a VB commodore intake manifodl on a HQ 253 no problem. You will need to blank off the pollution (EGR) hole wit h aplate oyu can get at most auto stores.

                thanks scottI have hz 253 i am putting yellow terra heads on but they are non pollution and I didnt know if if the exhaust port caused any problems.
 I guess the choke heater holes wont hurt .
 do you know anything about cam timing with variable gears.
