IMO, I would hold off until you build your 383--why pay to do things twice? Now if you plan on selling your 355 and purchasing or building a 383, then that is one thing, but if you are planning on turning your 355 into a 383, hold off. You will want to change a lot.
Your present cam is a good choice for a 355, and if you upgrade to a better flowing set of heads, choose a head in the 180-190 cfm range with a combustion chamber around 64cc's. 200 is too big--better for a 383 than a 355. Depending on how much you want to spend, AFR, Profiler, Brodix, and RHS aluminum heads are very good choices.
