1998 Formula Heads Im trying to look up the casting numbers on my heads and on one side its 208 and on the other side its 306 I've tried looking the numbers up to get the specs on them but I can't find the numbers listed anywhere. So if anybody has any links please send them my way. Thanks for the help.

Am i looking at the right numbers? They have some listing inside the heads but they start with like a "f" or something like that. The ones I listed above come from the outside on the corner just below where the valve covers bolt on.
