Just wondering if it's possible. Does anyone know if it would work, or if it would be worth it, if it were possible?http://imgboot.com/images/bdranck/img1077.jpg

Savage has done similar but only using heads

Looking at the rust in the middle inlet port, I would be wary, plus is missing a lot of essential bits

As madmagna said.
Personally I'd just throw a really aggressive cam in the car haha, far cheaper and although not the same I'm sure the results would be comparable? (Large assumption here, correct me if I'm wrong)
