if your motor is stock, I would think adding smaller chamber heads alone might not be a good idea.... a cam change would be required in order to make the most of the higher compression, assuming your stock heads are 72 or 76 cc, vs. the 64 cc of the vortec head.

If you're not planning to change the cam, I'd rework my stock heads or buy a set of Dart Iron Eagles with the same cc as your stock heads.
