305 head question

I have stock 305 heads(1.84 with 58cc)

World has a 1.94 valve head with 58 cc chambers.

How much more power would my 305 set-up make with these heads?(not including the n2o)

LB9GTA, I know you have been around here long enough and have seen my combo. If you want different heads I think the vette heads are a great choice. They are working well for me anyway.
