Need some head, help

Yeah the heads have been ported and polished, the motor is all ripped apart right now getting a new cam and swapping intakes, the heads would just need to be unbolted, I have yet to hear back from the seller with the J heads I originally planned to swap out to magnum heads but now we cant find the lifters or pushrods for the magnum set up so it would cost quite a lot of money for all that, not to mention having to purchase and intake for the magnum heads, I would be approaching like 500.00 by the end of a magnum swap.
