Question 454 Ho

My dad and i just aquired a 454 HO long block. It has the big rectangle port heads all the forged parts roller cam, etc. What can i do to this motor to get some more HP out of it. I already think i am going to get a set of aluminum heads for it. I have the same exact motor in my boat now and i may build it for a spare or for another boat. P.S. Supercharging is not an option.

Diff Cam Good Aluminum Heads And Change The Compression. Better Exhaust.
