I would consider flat top postons with valve reliefs in them and then mill your heads some and go with a small gasket, this will help to retain some DCR so you dont lose so much low end power. I cant say though how miuch you can mill though, you can get a clay test done before you do it all and it will tell you how much you can mill.
