exactly what the post says what size of bolts do i need to eliminate these?? Also what gasket is better the fel pro 1406 or the 1470?

 

what headers do you have?

the 1406 is what most guys on here use so i went with them and can say they have held up a year after i installed my headers.

 

5/8 inch brass plugs will fit perfectly inside those tubes. They also look pretty nice too.
And yeah, the 1406 is fine for your application.

 

If you are putting block off plates for the EGR valve and EGR pipe on the back of the intake manifold, you will not need any additional hardware for the EGR stuff. Both components are held on by nuts and you can reuse the gaskets with your block off plates.
