    Stronger main and headbolts

    I am building a forged engine for my Galant
    Engine will be put together with Prism H-beam rods, CP custom made forged pistons and new OEM bearings
    Will also be using OEM metal head gaskets, but the bolts will need replacing. Have no personal experience of it but people here have experienced head lift with stock head bolts, hence the need for stronger ARP bolts

    Know that others have used ARP head bolts for this engine. Just don't know if they were custom made or does some other engines bolts fit?
    Found out that at least the SOHC Lancer 2.0 NA 2002-2007 uses the same, maybe others also

    Have found out that the main bolts holding the crank has the same MD number as the Evo ones

    Which is nice because ARP does main bolts for the Evo

    Get two sets of the ARP head bolts for Toyota 3SGTE. Have them in my built motor, assembled, haven't installed the motor yet.

    Thanks for sharing the info
    Then the only ones still not known are the 4 main bolts with smaller heads.
    They should have the same dimensions as the other main bolts, but their heads are smaller (14mm)

    Turned out that the EVO ARP stud kit (main studs) actually have smaller nuts than 17mm, so they clear. That means two Evo sets will work in the 6A13 engine
