(IN REGARDS TO THE DOHC POST)So why does your little website even exist....what is the purpose if someone -who doesnt have all the time in the world to work on cars-asks a question to LEARN about them and all you smartass people have to pipe in with all the remarks....big deal..someone told me that i should throw on dohc heads on my ride and all i wanted to do was find out about doing this...so sorry that im not a mechanic....thanks for nothing
