Edelbrock heads for 289 in a 66 mustang? + how much horsepower? Please Help!?

So i have a 1966 mustang and am looking to add a little more get up and go to the beast. i was wondering what heads would be the best to add power and performance to my stang. Right now i have a 4fb edelbrock intake, a new edelbrock 4 barrel carb., and some classic k code exaust manifolds connected to flow master exaust. any tips would be greatly appreciated.

A high performance cam and lifters would do wonders, in fact the heads won't do much good without them...You might get 300 hp with just the heads, but add the cam kit and your talking over 400 hp!Edelbrock heads for 289 in a 66 mustang? + how much horsepower? Please Help!?
first i would get rid of the k code stuff and put on some good headers. less weight and twice the flow. you should have flat top pistons so some good heads will help out. the 289 heads don't have hard seats and have the "motor ruining" pressed in rocker studs, not to mention the worthless rail rockers that continually chew up valve tips. you are sorta at the cross roads,,,how many miles on the 289? what shape? to replace the heads you are going to have to tear it down so... maybe a cam and lifter change, electronic ignition, maybe forget the motor for now and do disc brakes. or a suspension change. rear end, slapping a set of heads on that old motor is a lot different than an intake carb swap and going to be a lot more expensive. its only time and money. good luckEdelbrock heads for 289 in a 66 mustang? + how much horsepower?

the only other way to make your pony gallop is 302 windsor as it is bolt in replacement for the 289 and there is a lot of stuff for making the 302 faster
ask edelbrock, but, before you buy heads why not put a decent cam and matching valvetrain in it?
