They are world products. They were on a 350(L98 i believe). I just want to know what size the valves are and if they are a good head to have. It says S/R on them and there is a casting number I-052. I have the opportunity to buy these from a freind very cheap and i was wondering if it is worth it just to have them, maybe incase i build another engine or something. thanks

 

sound like the world products Stock replacment heads. They come in two versions 194 and 202 valves. The 202s are called SR torquers and they are good for 350s in the 380 hp range.

 

then i guess for $100 ill buy them and keep them around
