i got aluminum heads on my new car, the guy said they are trickflows. they have NO markings at all, so i just did some internet searching. i found some people with casting numbers. sn "xxxx" casting number.
i went to the same spot on my heads, inbetween 2nd and 3rd exhaust port, same spot, and i have casting #sn18786
so with that, is this a trickflow head? has anyone confirmed that one of these unmarked castings, is infact a TF head with the sn casting number?
