5.0L 4v Head Exhaust Port
- Thread starter PaleRider
- Start date
The opening our CNC'd ones are 1.5" x 1.535"
Looks like O.E. is 1.425"-1.430"

Wow I heard that the 1-7/8" headers were very good for the GT 5.0l now it makes me wonder.
I thought the port was a circle?
looks like a circle, does not measure so.
1-3/4" on a n/a low revving build.
1-7/8" on a power adder car or one with head and cams
