a fan gave me a set of heads claiming they where vortecs, matched them to mine and they dont look to similar, number in the head was 14102193, and all it had for markings on the out side was 2 lines... can you guys help me out?

I didn't find that casting number in my 2003 GM Performance Parts catalog. The book shows a Vortec casting number for iron heads to be 10239906.

The GM aluminum head with a Vortec design has casting number 12367713.

They are not vortec heads - they're the common "centerbolt" heads. 87-97 I believe, 1.94/1.5 valves.

What are you planning on using them on?

I know guys that have hogged out the runners and put in bigger valves and i am sure it made a difference but still those heads were designed for 4500rpm or less and making torque, not flowing air to make HP at higher rpm's. I would prob look for something else but I am not saying they cant be made to work either.

If it's just a "spare" and "one race" then I'd run them as-is just for the one race and find something better to put your money into - like a "real" set of Vortec heads.... Those heads won't take a lot of cam lift as they are right now, so keep the cam mild - if you're running a high lift cam then you'll have to do something to the heads to make them even work.

id agree with brianw if it is the only thing keeping you offf the track then go ahead and use them but dont put a lot of money into them. IF you have the time the big gains would come from opening up the intake ports around the valve. There is sort of a ramp there that partially obstructs airflow, removing this will help a lot. Still not a good head but will be better.
