There is no part number for Total Seal,
when you get your ring set, you send your 2nd rings to them and they make them.
I had to have my heads done all over again. That costed me 300.00 I didn't really need to spend. I am into it for 850 bucks now.
I don't have time to mess with making my own stuff, I could but my time is money and I don't mind helping other guys business grow. I surely understand the pride of saying I made this and the saving, I am self employed so if I am not working I am broke. I sent you a message with my number if you have any questions give me a call and I will tell what I know which is not much, other than what I am doing to my build.
I was just talking to Ford 88 about using O'rings around the cylinder and modifying the head gaskets. Not sure about this yet.
