Eddy heads. Can I/Should i...?

You should see good results. I went from MP 360 Swirl port heads,stock with 188 valves, to eddy 60779's out of the box. I picked up almost 3 tenths at the track and 30 rwhp, have dyno sheets to prove it, with just the heads..
Bottom end is a 9-1 360,40 over 274 comp extreme cam, headers. With an Airgap intake, took off the M1 single plane, 284 MP solid cam,holley 650dp with proform center, I gained another 20 rwhp... not to mention the 50# off the nose..Your current heads are probably 68-70cc chambers, so you should see about 1/2pt more in compression!!!!
