Dan,,, you have old Barton stuff from marvel/bàughman,, going by what Eric says they are illegal,,, everybody at Indy this year was illegal going on what Eric says,,, if you see the valve cover bolt hole exposed in the int face,, it's illegal,, rule says int face may not be cut into any part of screw hole,,, any part,, tech says that means at the v cover sealing surface,, but if you listen to Eric and go as written,, it's any part,, so if that is enforced,, I'd say one person will have the advantage


We need this clarified

Happy thanksgiving to all

Jeff
