This Executive Order is granted based on submitted emissions test data which showed that
the worst case cylinder head, part no. 1470, did not adversely affect tailpipe emissions
during comparative Cold Start CVS—75 Federal Test Procedure. A 1995 Ford Mustang was
used as the test vehicle.

Difference        0.04     0.6    0.1
% Difference      33%      50%    33%

Test results showed that tailpipe emissions during comparative Cold Start CVS—75 Federal
Test Procedure with the Ford Aluminum Cylinder installed on the vehicle did not cause
exhaust emissions to exceed the baseline emissions by more than the allowed limits of 10
percent or 0.1 grams per mile on hydrocarbon (HC) and oxides of nitrogen (NOx), and 15
percent or 1.0 grams per mile carbon monoxide (CO) as specified in the "Procedures for
Exemption of Add—On and Modified Parts".                                        '
