318 rebuild suggestions

I went ahead and picked up a used 318 since I am missing numerous pieces to my original 318. It is a 74/75 year block with stock heads #3769973 1.78/1.50 I Do not know if the springs and cam have been changed, it is possible that they have. From looking at the motor it has been rebuilt, but do not know how long ago. It has an Edelbrock Streetmaster intake and needs an alternator and carburetor.

I was thinking of dropping it in and hoping for the best. But since I have some work to do on the car and drive train I may do a simple rebuild before throwing it in. If I go that route I wanted to know what would be a good intake, cam, springs, lifter, push rods, rockers,timing chain, distributor, etc.

I would most likely leave the lower half (pistons and crankshaft alone, unless that is unwise). I think I would go with a Holly 600 4brl carb unless that is no good (I do not know anything about carburetors, this is my first one, always been fuel injected). A little further down the way I would like to add headers what recommendations would you all say.

This is going into a 1969 Barracuda with the 904 and small rear end. My overall goals at this time with this motor is to have more power than stock but I do not need any crazy horse power. This car will not be raced, just cruised around.
