    Picked up a head from a 95 or 96 gsx It looks like they had some work done to the head and then the car didn't start, (had new cps/cas headgasket and other electronics.) So they junked it. I have a few questions. I don't think these are stock valves because they don't say 6t, does anyone know what brand they are? Also it has this stamp thing on it, does anyone recognize it?

    Not sure about them intake valves, but that's a reman tag if I'm not mistaken. Edit: Does this head have the small or big intake ports? I pulled a head from a Hyundai at the salvage yard once that had a tag just like that.

    Head has small 2g ports. It also is 5.200" thick so I don't believe it was resurfaced ever. I also snagged a Hyundai head but it has bent valves.

    I personally have never heard of that. What Intake manifold do you run? Are you sure it's not a 1g head with a 97-99 CAS?

    Ah I just wanted to see of it was a hyundai head. The Hyundai heads had both large and small ports. Small port Hyundai heads has the 95-96 style cam sensor. I can't remember if the larger port heads did too. I never heard of a large port 2g head either.

    My head has the same exact stamp. I bought the head and block rebuilt from Overbore. Pretty sure most companies or shops add them.

    The intake valve are not stock, that you are correct about.
    Now if they are good for turbo use, I can not say untill you pull a valve and check for a part number on the stem.

    Now you can see if a magnet sticks to the head of the valve
    If it sticks.... NOT a stainless steel valve, could be a cheap replaement valve

    If the magnet does not stick, then it should be stainless steel, but still needs looked into.

    I doubt theu are stainless tho, the sharp edge in the valve leads me to this.
    Most all decent made stanless valves will have a smooth dish built into them.


    Now that little part that is stuck on the head is called a heat tab, the center will melt out at appox 260* letting the company know the head was over heated, and voids any warrenty you may have.

    They are commly applied by Machine Shops, Junk yard, engine rebuilder. head rebuilders.

    Cool! I tried the magnet trick and they stuck to the intake valves, so they are not SS valves, but they would only stick to the edges of the exhaust valves. :confused:

    I assumed none of these were stock valves.

    I'm still looking for a valve spring compressor to remove them though, sadly.


    One other thing, if these are not good valves would I need new seats if i bought a set of engnbldr ss valves?

    If you get a full set of valves, I would recommend that you have the seats cut.

    Also at this point I would have the guides checked and replaced as needed....

    If you are going to keep boot level at 20ish, Iron replacement guides will give you a decent life.

    If over 25 I would suggest going to a bronze guide, due to the extra heat that the valve will absorb and pass to the guide.

    So I finally got around to checking onto these valves. After removal I recognized the symbol and after a quick Google search it seems they are "sealed power" valves. Does anyone know if they are any good?

    Sealed power is a large corp, they bought out TRW about 15 years ago, I think they own Ancco wiper blades, BWD componats .... But the mother company is Federal Mogal IIRC.

    The valves are pricy, and I do not know if they are a 2 poece design. So run them at your own risk.
