    There is a Lot of potential in the 225 , I ported the heads & milled them .100 to increase the compression , there used to be some decent cams from Mopar , Clifford may have some Lunati has some killer Mopar grinds . I have not looked into voodoo cams for the 225 but a call to Lunati would answer some questions . Header maybe Clifford , 6-1
     Hooker has a 520=5602-1 from Jegs

     I use the Holley 390 4 bbl awesome tunability & very responsive with the 4 bbl intakes , you need to build a brace to support the Hyper intake long rams & it will be difficult to tune using a long ran as the carb never gets heat , but I have out run a ws6 car though 1st & 2nd gear .

    porting=open up the intake and exhaust ports by grinding away some of the metal so they flow better.
    milling=cut down the mating surface of the head (to the block) to decrease the size of the combustion chamber therefor increasing compression

    Is that something you take the engine to a machine shop?

    You can just take the head to a machine shop.
