    shaving heads

    how far can they go on a 250hpdi and still run on 93? theres a few extra sets of heads laying around and we want to tinker...

    also, will it make a difference when a series 2 powerhead is swapped in?

    HT is not gonna give up the recipe... Tinker you may, But I would send them in to HT to get the work done. It's cheaper than you might think.

    Mike as always is right. I would rather let hydrotec do it, if it's not done right you will take a chance of ventilating a block.

    They have done all the Dyno testing torture tests and reserch to know what is too far with what gas ect.... a set of heads from hydro tec is cheeper than blowing one up while you experiment.....
