Good mods to make torque in a 440

I would run the sidewinder heads over the 440 source heads.Have any "ready to run" head checked before bolting it on.

Stay short on the duration and torque will be available everywhere.Might even be a candidate for the Hughes Whiplash cams if you want the rumpity idle AND low rpm torque.


Intake will be fine with a used Edelbrock performer or any dual plane.

As far as stock heads go I would use with the best flowing heads I had regardless of compression.I will take a 20cfm gain over .25 or .5 to one increase in compression all day long.You can always mill the heads cheaper than you can pay some one to port them.
