Josh, really, can you see how it will be difficult for any of us to help you if you don't provide all the information? Forget about the damned suffix code and post the head numbers. And to answer your question, "why does it have a 8 and not a 3"?....... It doesn't have an 8....... If you get in there with a fine-point pick and scrape around, you will remove the crud that makes you think you're seeing an 8.
I'm through here until I see some head casting numbers.
