I'm looking at a set of J heads later today that are supposed to have the 2.02 intake. The casting numbers are 3418915-G and the other is H. He says 360 is also stamped on them. He sent pics, but I can't see the 360, just the casting #'s. I have tried to look the #'s up and have found a lot of conflicting info. I can only think to bring a micrometer and measure when I go, but would really like to avoid a 1.5 hour drive down there if I can verify they are not 2.02. Any help would be appreciated.
