I am considering investing in some aluminum heads. The cost to rework the 452 or 906 heads I have may be better put towards a set of aluminum.

But, does anyone sell a ready to bolt on a go aluminum head? I know several sell complete heads, but I have seen many posts about having to have them torn apart and checked, or reworked before they can actually be used.

I know Edelbrock, 440source, and one other company (the name escapes me) sell complete heads, I just want to be sure I spend wisely if I go that route.
