That swap is pretty popular. So popular, in fact, that Ford did it for the Cobra motor. It not only gives you more valve lift, but it increase the duration just a smidge - like 2-3* on both ends. I did it to a stock Dodge 5.9l gas engine, it made a noticable increase in power, and improved gas mileage a smidgen.

The question is, will it work with your combo? Without knowing exactly what you have, it's a WAG for anyone. You'll just have to get out the dial indicater and do some research.
