<VV> Top cover gaskets/loose screws

Clark, they were able to make the aluminum heads work on iron blocks
because the temp range was more steady and narrower on the water
pumpers than we have on these air pumpers. Our engines had shrouding
around them to try to produce a more consistent temperature to help
mitigate those issues, too. Mark Durham

Another reason screws loosen up is cover and block are aluminum and the
baffle is steel.  They expand and contract at different rates causing the
gasket surface to "walk" back and forth.  I never could understand how
aluminum heads can work on an iron V8 block.  Lots of movement there!
Maybe we should make an aluminum baffle plate.
