That is correct, most of you power comes from the cylinder head. So lets just focus on the head first. First, do not angle mill the head. There is no virtually no power to be gained here and only causes a ton of headaches. It not worth all thats involved ( jigs, angles, machining headbolt seats so they will torque evenly). Instead, I would go ahead and mill the head to about .150-.165 or just before the intake bolt holes. Always make sure you shorten the head bolts, alignment sleeves and adjust the cam timing accordingly to compensate for the milling of the head. In my opinion, the D port head is the best. It has smaller ports which creat more velocity. But with intakes installed, the oval port with a d port intake flows slightly better. Your cam choice is not a bad one. I would go ahead and double check your clearances, and wear patterns on the followers. Make sure you don't have excessive lash and cam in riding in the center of the follower insert. Spend some time degreeing the cam, there alot of power to be found here. Some good carb work and freeing up the bottom end always helps too.
