Default What heads are these?

What can you tell me about these heads #338882? It is not the original motor, went from 307 to 350 about 15 years ago. My grandfather did all the work and now I'm trying to figure all this out. I went to autozone to get new spark plugs but they were too big, wouldn't fit in the hole.


Driverside head


The engine is a remanufactured 350 but I don't remember if the heads came with it or we used the ones from the 307.

Nothing special, used on a bazzilion Small Blocks. They use a taper seat plug like the R43TS

Thanks guys. I saw those casting #'s, but is that a typo or do my heads have a typo? Haha! 338882. I was just worried that my heads were from a smaller engine and the spark plugs that autozone calls for are beefier than the ones I have now. The plugs I have are bosch platnium HR9APX.

Casting # 338882, Built from 1970 thru 1986, 882's are open chamber 76cc if memory serves correct. The right plugs are tapered and will take a 5/8 socket to put them in. Dont get these heads hot by no means.
