someone forgot which screen name they were logged in on, lol. threw me for a loop at first, Ben.

You don't have to worry too much about going too large because you're honestly not going that big in the grand scheme of things. The engine works as a system and needs to be designed as such. Focusing too much on one aspect will cloud the overall picture. Too much cam with too small of a head will kill low end just as well as too big of a head for the cubic inches will. In your case, I would go with a 200 or 210cc runner head and match the cam accordingly. You'll also have to match the intake, carb, and exhaust.

For reference, look at what LS engines have for runner volume and where they make power.

Also, I'll be going with 200cc heads on my 383 LT1. I'd go bigger but I'm limited due to being an LT1. The motor should make about the same power you're looking for as well. My intake and cam are coming from the same company that does the heads. They've proven their setup works. My headers and exhaust are sized for street power which is why I only have 1-3/4 primaries and 2.5 inch exhaust.

Good luck, Ben. Remember, average power under the curve is everything.
