    Nice, but i believe I've heard others say not to polish the intake?
    Seems they say like an 80 grits sand paper feel to it?
    Have you heard this?
    Thank for the info!
    😇🙏👍

    Great video, what does this translate to as far as power and speed compared to non ported heads ?

      @@c-los4630 its a noticeable power difference. You’ll be able to feel it . I don’t have a flow bench to show the difference between stock and ported . Also I’m gonna make another video bc I over did the entrance of the intake port . You don’t want to over port because it will slow down velocity . You want to speed it up in the entrance and slow it down at the cross section . I’m fairly new to porting and learning a lot but I will definitely make a new video

    Suggestion; you may not want the radio blaring as your showing what your doing?🤷

    So you loose velocity if you open it to much

      Wish I would have known that at the time . Ty for your comment. I’ll make another video with that correction.

    That head looks to be ported already imo. What casting is that? Yeah I would bet money that head has had port work already. People- be careful, I'm halfway through this and following this if you've never done port work before, This process could definitely have you removing WAY too much material! Remember, it's about port VELOCITY, IMO just as, or more important than flow.

      It’s a predator 212 stock . It’s been used but not ported . I wouldn’t do you guys like that .

      You can also zoom in to see that it’s stock port .

      I think it comes down to what you want the engine to do. A head like this should get max HP at a higher RPM than a head with less porting.
      The caution would be for those of us that don't run our engines to 7500 plus RPM. A lot of us are doing basic builds with 265 or less cams. You wouldn't want all this porting for that.

      @@Deucealive75 I did notice that a head that had slightly less porting performed a lil better at lower rpm’s . I’m using a stock cam which is a 210 lift .
