Sherman has chosen Cometic gaskets to seal the deal, and while some readers may never have heard of Cometic before, we're confident they will in the near future. When asked why he chose Cometic, Sherman responded "I called Cometic to ask about their products, and after I heard about all the work that has gone into these designs, I wanted to see them. I watched a NASCAR race over the weekend after I'd called, and saw their decals on several Winston Cup cars. I decided to run them on my entry, and the more I've looked into the materials and engineering on these things, the more I like them. I expect to use Cometic gaskets in plenty of future engines. Look into them yourself and see why." Cometic's spring steel designs are new, and they offer builders the option of custom-sizing gaskets for odd bore sizes.
