If you have the J Code 4V heads they will probably hurt performance. The J code heads have small (53CC) combustion chambers that increase compression. The E7 heads do not flow much better than a stock 2V head. The power that the 94 GT gained is a result of roller technology and better exhaust manifolds. And there are some installation issues. IMO they would not be worth the effort. Here is a nice discussion on the E7 heads:
