That is the right guy to send them to. If Dwayne did the heads then you should be ready to go. He'll probably have a record of what the combustion chamber size is too and he can provide you with a cam recommendation if you don't already have a cam.

Do you have a Stage VI intake? If so, 4150 or 4500? You'll need a 4500 intake and carb to make the bigger power.
