    Default no exhaust gaskets?

    newbie question. i took off my headers to make it easier to work around getting the motor in the boat and when i took them off i noticed there was no gaskets. are marine set ups different than cars? if they are supposed to have them could i just use some automotive gaskets or do i need marine? thanks.

    Headers require gaskets on a boat motor. Measure to port size and shape and check your local parts store. If you can't find them. Post the engine type BBC or ford, port size and shape and somebody will give you a brand name and part number.

    Some people confuse headers with log exhaust.

    If they are true headers, Wicked hit the nail on the head.

    If you are referring to logs or manifold exhaust, Left'y Pride hit the nail on the head.

    Different applications require different answers.

    I find a good deal and usualy keep a set or two lying around. Every time i yank the headers off the gaskets are allways eaten up... Cheap enough to replace and Autozone has them locally. You can also shop online at like jegs or summit.

    I got tired of buying regular gaskets and replaced them with copper exhaust gaskets. I found a source for copper gaskets for Bassett Headers. Let me know if you want a set. Pat

    log style DONT USE A GASKET. you will regret it not right away it will seal but after a season you will find that the flanges warped and now there off to the machine shop where they could not do the job with out taking the risers of where you will swear up and down taking them apart, then end up scratching them (more swearing) send them back and finally you think your done and a year later you start to see stress cracks around a couple of the flanges....... believe me i did it just go to the parts store and but copper seal silicone (extreme temp) get the glued on there and dont look back plus every time you take them off you dont need to run out and buy another gasket just glue more on. believe me my uncle did this to my boat before i got it, and i had to deal with the rest

    Have tried with and without...both regular and copper. What motor you running? If its a ford, the only logs n snails that will work correctly are the through bolt ones. I have em on my ford after constant attention to the flange type. Got my felpro gaskets at beans in elcajon...They never leak!

    Do your logs have the split/cut in between each exhaust port? I would run good a set of gaskets, but no need for copper.
