I am in the prices of putting a head and base gasket on my 83 ATC 200 and I have a few questions. Do I spray permatex copper on the gaskets before install? I also bought a top end gasket kit (winderossa), what are these other o rings for? How do I get the o rings for the dowel pins to go back in the head? Don't know if pictures posted but let me know. Any help appreciated thanks![]()
