I bought mine from a machine shop. I suggest using viton postive seals and not the umbrella style.Although if you doing a stock rebuild and want some umbrella seals Ill send you the ones that came with my Mr Gasket engine gasket set.There brand new and still in the package. Heres a link for some at Jegs there 24.99 http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=2586&prmenbr=361
