Yoyo, I've built and run numerous 221's, including the L100 and Fenton twin as you're proposing. I agree with Ron; the L100 is not a good cam in this application. Try an Isky 88 cam along with your other mods, take the lip off the flywheel, use a 9" clutch, and yes, port the block. The idea is to lighten everything as much as possible and allow the thing to breathe. Enjoy...
