Trying to decide which heads to go with on my 440 build prefer to already have them CNC and ported when I get them. Already have and Performer RPM intake manifold have not decided on cam yet but will be going with a 500" stroker kit. Here are a few choices that I am looking at.

If I go with Indy is there anything that I will need to change or add to my engine?

Car will mostly be a cruiser maybe every once a awhile to the strip don't have as much time now days for that with 3 kids and a wife. Will be keeping non-power brakes so not to worried about cam. Over all I want a strong engine with plenty of torque and a mean sounding idle. Parts are all I have to pay for on this engine build. Getting it put together for free just looking for more opinions.
