More exhaust valves are failed from incorrectly set up and regulated O.T. headers than anything else! The higher the HP and RPM the more you need better valves. We use Ferrea Super Duty valves in the good stuff with O.T. headers, you can drop back to the Special Alloy for Lightning dry type exhaust. Less HP, like hydraulic cams, we use a minimum of their 6000 series. "Get away with" and exhaust valves should be a mutually exclusive deal. You can stuff a cam in anything, but how long will it live? TIMINATOR
