Yeah, he knows the head needs to be machined, and I think it will be or is going to be. He asked if I knew the part number or the application or for which car. I don't know, I told him about the other ones that drop right in but it's cheaper for him/us to get Yanky parts in Yanky land. Plus the price, postage and the slim chance of it getting lost in the post is putting him off. So bump to see if anyone can help. If it's easier, you can email me. ecotos@yahoo.com
