You don't need to over bore or stroke if your goal is only 200.

Stock bore
12:1
Rods
knife edged crank (free up a couple more ponies)
Jun III's
valvesprings
retainers
Skunk 2 intake mani

you should be around 200 whp with that setup possibly more if tuned right, thre is more to go into a setup than that but it is kinda late and i am tired.
