    Re: hydro-tec heads (tr21alabama)

    tr21 i have measured the hydrotec heads for the 2.6 a couple different times and compared them to stock heads and from what i see they are milled the ht heads on my motor are .030 thinner than some stock 200 heads i have and .020 thinner than a stock 225 excel heads. but i have asked the same question and was told that you could not mill yamaha heads but was not told the reason for it.

    I sent Hydrotec my heads and had them cut (VMAX 0X66 225) --no problem.
