  2. In and effort to reduce the spam on the site, several years ago I had went to a program where I manually approve each and every new registration. This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

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).

    TA 1517X 350 Heat Crossover Plug Kit ................ $6.00
    TA 1518X 400-430-455 Heat Crossover Plug Kit .... $6.00

    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.

    Is the picture the final product, or do you still need to fill after install?

    Thank you!

    I had bought my own plugs and been running the car for a couple years and was wondering why was my performance that of an old tired SBC...
    I came back to find member who had heads for sale and am now wondering, did these plugs come out, is that why I am suffering with poor performance with all these upgrades.. Trying to look through posts to find member from around Eau Claire WI area who sold model cars, he told me he had some heads...
    but I would stake every plug in case those under the intake, in the center, come out.. I would expect it to pop, and it wastes a gasket in the process, to find out if they are leaking...
