    Question SBC Exhaust Manifold Bolts

     





    I have a 1981 Chevy 305.
    I am installing a set of Rams Horns on it.
    However, all the mounting bolts were lost.
    I was told that these bolts are 3/8 x 16.
    8 of these bolts are one length and 4 of them are longer.

    Does anyone know what length each of these bolts are?

    Also, 1 of the bolts/studs that holds on the exhaust pipe is missing.

    What is the size of this bolt?

    And there are 4 small plugs with square heads on each manifold--

    What are these plugs called?

    I was told that these plugs are 1/4" NPT---is this correct?

    If anyone has any of these bolts, I would like to buy them.

    Contact: Mike--407-953-5007---drumdoctor at live dot com.
