Trophy Stock - GT-40P question
 

Central Coast Mustang sales the GT-40P head with modifications that allow regular exhaust headers to be used with these heads. I was wondering if these heads would be legal for Trophy Stock with this modification. Thank you, Jerry.

Standard shorty headers will fit these heads as-is, with no modifications. Use the Accel "shorty" spark plugs to avoid clearance problems. Other than exhaust port gasket matching, no other mods permitted.
