What do you guys know about this E22 head. Ther is a guy selling them on Ebay for $55.00. http:\/\/cgi.ebay.com\/ebaymotors\/ws\/eBayISAPI.dll?ViewItem&rd=1&item=2481853250&category=34284\n\n\n\nIs this a good head ? How does it compare to a stock or a TB head as far as port and valve size ? I assume this head would require a domed piston.
