    With a heavy car and a small engine,gearing and a good converter would be on my list first,along with a good set of headers and dual exhaust with X pipe.As for heads,I would go with some stock casting with some match and bowl work,with good blending,3-4 angle valve job.You need a low/mid range cam,one from idle to 4500-5000rpm range with a dual plane intake to get some torque.The cam needs to be a 112/114 center line to operate booster and other item on the car,lift is around 450-475,duration should be around the 248-268 advertized.Do not go to a big valve head as you will loose power,and if you can,use some steel shim head gaskets to gain some compression,and mill the heads a good amount to get a good 9.5-10.0 C/R.mrmopartech

    Depending on the head being use,the ports are larger on some heads,so the 340 intake has larger ports thus a mismatch of port openings can happen,causing problems,as the volume in the 340 intake would be to large for the 318,mrmopartech
