I just put my intake on my 440 and ran it for about 2 minutes and realized I was leaking water from a stripped exhaust manifold bolt in the head. I need to pull the head off and put a helicoil in, what I am wondering is can I reuse the valley pan? It was brand new when installed it 2 days ago I did use a gasket between the top of the pan and the aluminum intake and a small amount of sealer between the pan and the heads, but not sure if once torqued if it can be reused.
