    Or just to add is a 100 for a skimmed AGU head good? Been trying to get a price to compare it with but cant find any other heads to compare it with.

    If you are being supplied a head already skimmed for 100, thats good, if someone is charging you 100 to skim it, thats too much.

    I think he means 50 to have it skimmed. If you can buy a skimmed AGU head for 100, that sounds good to me

    Normaly it means it's better except on yours.

    It's a larger port head, TBH you will not notice a huge difference on a normally tuned engine. It's not until big power where the small port/large port issue comes in.

    Small port heads tend to provide more tractability due to the air velocity, where as a large port tends to give better overall power

    Yes mate, it certainly is.

    Tuffty has still made a reasonable increase with a small port head !!!
