i would get a kit and clean it.......it's nasty inside.....
I just did a 650 holley for a friend of mine that he pulled out of a ditch......it was real bad, not saying yours is like this one but the fuel leaves a nasty brown glaze like chit inside them and bugs will nest inside the air bleeds and vents........
I had to glass bead this one inside and out, you would not believe how bad it was. I hope it works when I'm done, had to paint it red..looks good.

Stock head will flow just fine through 3000 RPM. If you are racing then the aftermarkent heads are the way to go. As for the orginal Q, the F4TE casting was my choice for the roller cam. I figured that those engine blocks would have seen a lot less friction in their time.

i thought that i would add on to this...i read today in an older mustang monthly mag that the 68 302 heads have the smallest combustion chambers and have 351w size valves. it was something i dont remember hearing before. maybe someone could find these heads instead of looking just for a 69 351w head.
