how are logs for performance??? I have some basset's.... over transom though that I want to replace with logs..... make it more family friendly.... I have flush tips, hose and bolts and gaskets that I bought last summer from Rex.... but the logs I bought off ebay will not seperate at the snailshells.... I have to replace those gaskets...... to bad you want thru transom.... I would trade.... any idea on how to seperate the shells from the manifolds... it is like they welded themselves together
