    Default 350/400-430-455 Cylinder Head Heat Crossover Plug Kits

    Hey guys,

    I've seen a few posts over the past couple of months in regards to people trying or wondering how to plug the heat crossover ports in their iron cylinder heads. To make this process simpler, we've created a heat crossover plug kit for 350 and 400-430-455 heads. The kit consists of 4 freeze plugs that you drive into the heat crossover ports in the cylinder head. Usually the plugs go in pretty tight but if they seem to go in a little easy, we recommend taking a punch and punching the corners of the port to swedge the plugs in place, just to be safe (see attached picture).

    I do see it in your catalog and tried to search by the number found to order a set, but results said nothing found...
    Otherwise what size plugs do we need, I am certain I could go to a local parts store and buy these separate and plug those for upcoming B4B intake swap.
