Every builder I've talked too about these heads is buy them bare and use quality hardware. That goes for all of their heads be it Mopar, Ford and that other company. I bought mine bare and had them set up for my cam and build.
Maybe they are using better hardware now so it may be worth buying assembled.
Yeah before I but mine last year I called Don's over there on Stark and they said at least $800 to rebuild them as everything was wrong with them. The valve guides the seats all had to be replaced everything. They said $800...
And again I ran mine out of the box for the most part and everything's been fine for the last year or I should say all this summer... But again that's just been my personal experience..
