318 LA rebuild after losing a valve seat

I didn’t even wait for your reply haha, just went straight to the parts store and ordered the composite set. I didn’t do all this work to “hope for the best.”

I suspect the sticker is some sort of heat sensitive sticker that indicates if the heads were run too hot, which would explain why they would want to see the sticker on a warranty claim. I work for the fire department, and we have similar stickers on our ladders that will change color when exposed to extreme heat.
