The 4V Cleveland heads can and will make more than adequate horsepower, I have a 391C in my car and currently building a 406C (.020 over with a 4" stroke) with no regards to originality in either build, and I do not see any reason(s) to bolt aftermarket heads.
With just minimal bowl clean up, one piece SS valves, checking/replacing guides, trued head surface,new springs and rollerized rockers, you are going to have a hard time limiting your 300 hp goal at that figure, even with a street performance hydraulic flat tappet cam you will easily surpass your 300 hp goal in a very streetable package.
