As far as power increase, no.

But you would get perimeter bolt valve covers instead !

Dont forget about valve covers, coil brackets, gaskets, coolant, new head bolts, maybe intake gaskets, and a port job to make it all worth it. It would be wise to wait and find a good set of ported factory castings.

NO WAY, THEY ARE TOTALY DIFFERENT.
Ported 241s should get 30+ rwhp if done properly.
