Do I have to re-balance this 360

I already have a new set of Eagle I beams laying here, Just trying to use up all the parts I have around. When you get up to 40 years worth of building cars you end up with a lot of spare parts around. I really have everything to complete this engine except a good set of heads but I'm heading up to the Indy winter show in a couple of weeks and I will probably get some of the Indy Lax heads to use on it. In addition to what I mentioned I have a Comp cams 305H cam and a set of roller rockers, a Holley Strip Dominator, a 750 Holley double pumper and a set of Headman big tube W2 headers and a Mopar Performance race electronic Distributor and a few other misc. parts. I figured that would empty up a little shelf space. I also found a MP3.58 stroke crank with 340 mains, an Offy Port-o-sonic, A performer RPM for magnum heads, a set of Edelbrock Magnum heads and a set of KB 356 pistons for a 4 inch stroke and a pile of various aftermarket magnum roller cams and other LA performance cams,etc,etc.
