"I have been reading that people are suggesting that you should replace your manifolds with in five years. I have a 1986, 440 that I have never replaced. I pulled them off two years ago because they were plugged up and cleaned them out and ran for the last two years without any problems. This year we went out and I think that they are full of rust again. I have been looking for they type that I have and can't seem to find them any where,If any one can let me know where I can purchase the type that I currently have I would rather do that. The other question that I have is could I take them to a engine shop and have the boil them to get some more use out of them."

My friends uncle runs it, and I asked if they could match the price I got off the website, he told me to get them, cause they couldn't come close. Just shop around, you could save a bundle out there"
