i have aluminum heads but dont know what they are.. the serial number is 117977 or 17977 i forget which one it is an cant see it since they are installed

 

OK cool!!

 

ooookkkkkaaaayyyyy.

How about the brand, or the company you bought them from, perhaps the intake runner volume that they advertised or something?

Or if stock, the casting number, which is stamped below the rocker arms on each head...

 

there is no other numbers or name on them.. my engine builder put them on.. an hes an idiot an didnt know what they were but they made just alil under 500hp.. so i wasnt complainin

 

Do you know what BRAND the heads are? Dart? Edelbrock? TFS?

 

hmm idk.. thats what im trying to figure out obviously..

 

Well, usually its cast or inscribed into the head somewhere... usually either on the side, between the exhaust ports (if its cast on) or inscribed into the front machined surface where the alternator would be bolted on.

Also, sometimes there is something cast somewhere under the valve cover. On my cousin's Edelbrock heads (on a Ford 390) it has the Edelbrock "E" logo (looks like a big backwards 3) cast in. Maybe your heads have something there too?

Worst case, you could always check out a few of the manufacturers catlogs and see if you can find a matching part number.

 

ive looked through summit an jegs online an still havent figured them out.. i think they are old TFS. but im not quite sure

 

Pictures could really help indentify them. Someone may be able to recognize them for you.
