Default chaning heads

Right I have a 383 with flat top piston with 2 valve relief,230/230 cam and home ported heads ( 882) .Not sure how this will run on the street
still putting car together .Thinking what I have been reading I can go with 190cc/64 cc chamblers 2.02 /160 valves if I go that route will that put me out of pump gas range?

Not certain with the flat top pistons, I am running D-dished with 65 cc, 2.05/1.6, 195 heads and it is a sweet setup.

I did a set of 882 heads once on a 327 and was not happy with the results. Needed more compression.

I know I will be dating myself, but how is everything in Avon Park ? I graduated high school there in 1963.
