    hi, i bought a big valve head for my vts and am putting pt50k kent cams and vernier pulleys on it. i was wondering if it was best to get it skimmed and pressure tested before i put it on. ????

    if then head is new then no i wouldn worry about getting it skimmed, but if its second hand it would pay to get it skimmed

    ok, is it not worth doing to raise compression? rather than peace of mind

    there wont be bugger all clearance between your valves and your pistons if you skim it to much.... it will be close as it is with thous cams.

    About the camshafts... A waste of time IMO. Go for some 51's, or Catcam 708s or Newman's PH3's. PT50's will be hardly worth the bother.

    as toad said pt 50s are a mild and (pants cam)

    Re head skimming im not a fan, remeber the more you keep skimiming off the more chance of having the head written off if you have a HG failure and warping of the face

    you also dont need vernier pulleys as std vts ones are adjustable

    Skimming doesn't cause gasket failure or warping, don't know who told you that!

    what he's saying is, if you skim the head to lower compression if your headgasket did go you wouldn have enough metal on the head to skim of to correct the warp. hope it makes more sence

    Ha! Since you were in a correcting mood, I thought I'd give you a dose of your own medicine.

    I know mate. It was good that you did, as I think he definitely got Ryan's comment confused. Good stuff.

    perhaps you should take reading lessons before trying to correct me again

    depends on the budget you have and how far you want to take the engine.

    there is no 'best' set of camshafts for all

    he'll have over 2mm clearance with those cams imo, they are very mild so will prob be near standard which has 3.5mm, lots of clearance.

    Few questions in relation to items mentioned a n00b in this thread:

    I know that the standard pulleys are adjustable, but isnt there an advantage of a lighter
    weight adjustable pulley? Or is it a waste of time bothering?

    Also, if you ever needed your head skimming due to it being warped. Your saying that having
    it skimmed may mask the issue but mask it worse later one?!


    Im so uneducated with regards to cars man. Cheers Ry bab.

    nah, what he means is, if you skim too much off your head in the 1st place. then at a later date if your HG goes and the head warps, there wont be enough material left on to repair it.

    Ah right I see. So in that case a brand new head is needed.

    yes, but i doubt you would skim a few mm off at any one time.

    rushy, standards being adjustable for cam timing is all you need. The only reason to upgrade in 99% of applications is due to the original pulleys not having the ability to adjust the cam timing with (8vs for example)

    Re the head, as williams has said. The head doesnt have an infinate amount of material on it, so if it gets skimmed for no reason there is a higher chance in the head being written off if it gets warped through *for instance HG failure* as there is not the material there anymore that could potentially be removed to have a perfect head face.

    make sense?

    All pretty self explanatory when you think about out. Cheers man.

    why they allways say, if it aint broke dont fix it.

    Its ok to write off a standard head but think if you have had extensive headwork you dont want to be skimming bits off willy nilly and risk a long term loss.
