Spark plug for eddy heads? - 08/27/08 05:03 PM
Which spark plugs to use for big block eddy heads? Can't get a socket on the regular champion RJ12YC. Thanks.

There not the same plugs. The RJ has 3/8" reach and the RC has 3/4" reach. Thanks.[edit] But I just learned the edelbrock heads require the longer reach. So the RC12YC is the right plug. See ya
