Gen 2 3sgte head

Hi all,
 
Recently rebuilt my 3sgte but there was some significant damage to the cam journals from past owner and was unable to get it 100%, one or 2 of the buckets had a slight tap as the cam was floating around a little, anyways i started the car yesterday and It is quite noisy now so looking for a replacement head. not looking for anything already reconditioned as I have all the machinery to do it my slelf. Also anyone know what changes to heads through the 3x generations? ie will a gen 2 head suit my gen 1 block/manifolds? just having issues finding anything gen 1
 
thanks, in advance.

    Yes gen2 gte head is a straight swap. All your gen1 manifolds will bolt straight up, also allows you to fit more readily available aftermarket cams and valves.

    I've got a Gen 2 head, looks in fairly good condition.  I've also got manifolds, TVIS, exhaust manifolds, etc.  Basically everything that attaches to the head.
     
    PM me if your interested.

    You can also use a gen1 ge head from an st162 celica, but better to go gen2 if you can.

    What vehicle is this motor in?

    Are you sure its a gen1 3sgte? It should be a gen2 3sgte.

    Not to confuse the sw20 revisions with the engines. 89-93 sw20 came with the gen2 3sgte, tho they made a slight revision to it in 92, more on the ecu side of things than the motor.

    Only the st165 gt4 came with the gen1 3sgte.

    this is real simple
     
    gen 1 3SGTe only used in celica. has 2 separate cam covers. NEVER in SW20. 
     
    there are 4 versions of the Gen 2 head. . all of them have a 1-piece cover
     
    rattles in the head usually come from incorrect cam tunnel clearances.
