I bought these heads recently. They were advertised as Blue Thunder heads with raised ford exhaust ports. They don't look like the heads Blue Thunder sells now.
Actually there is no identifying marks that I can read on them. There was something stamped on the end of one of them, but someone stamped a bunch of "X"s over the letters/numbers.
I measured the valves, they are 2.25" and 1.76".
Does anyone know what heads these are? Are they worth sinking some money into? One disassembled one needs the guides replaced, and they have quite a lot of porosity.
Thanks.
Jess
