    You can make 600 hp with stock oval port cast iron heads. You can put the best quality aluminum heads on and not get 600 hp.
    What I'm getting at is that 600HP wont be made with your heads, nor will it be restricted by your heads. The design of the BBC head is a very good design, and just port matching them to your intake manifold will work awfully well. With the right engine mods the stock heads will handle 600 hp.

    As long as those stock heads are not peanut port heads, and you can get some decent compression.

    post back the last three head casting numbers that are between the rocker studs.

    May be like a -215 or -063 or a -781 or -049??

    Or the PP head, the -236??

    Lets say you find a set for $100 get them decked,valvejob,checked for cracks,hot tanked,new springs.seals etc......
    Whats a port and polish job go for to get around 600hp ?
    When my dad did his 781s way back he had $900 into them and he did all the work himself.
    Id rather spend a little more and ditch the weight.

    Fwiw, Mark Jones, (aka, Vortecpro), make's GREAT power w/ his reworked over stock heads so go from there!

    No more than just a bowl-blend and a good multi-angled seat job on say, an old closed chambered -206 head, .020" thick steel shim headgaskets on a stock '70's to '80's 454 P/U engine will wake it right up b/c the CR. will be up around 9.2 to 1 so that a decent 270 to 274 cam can be ran!
