With the discussion on oil and cylinder head temps and engine cooling I'll remind everyone about the "homebrew" flexable seal material. It sells for about $4.50 a foot and you can make it for about $1 a foot. I came across this info at one of the Gatherings.
To build mine I cut 4 foot lengths of 2" fiberglass tape. Lay on plastic and squeegee in the high temp RTV. When first layer of tape is coated add a second layer of tape and coat it. I used 4 layers of tape and that seems just right. When the top layer is coated, flip the 4 layers over and coat the bottom side. Allow to cure and trim excess RTV from the edges with a sharpe scissor. You can't tell this stuff from the seal material you purchase. Larry Flesner
