Est Hp of 6.0 with 6.3 heads/intake?

I think you guys are suggesting a 243 6.0 head from either a vette or gto. a better and cheaper option then going to a l92 setup as far as cost are concerned with not too much difference in performance. they flow really well.
Biggest performance gain would be an aftermarket cam
good luck with your choices
