First time installing an intake.

drain coolant system first.... will need oil change when all is said and done.

don't use the end seals, use a thick bead of silicone (my preference is "Right stuff")

uhh oh ya lay the lower intake on with gaskets and check the port alignment, if it's off you may need to mill the manifold or get thicker gaskets.

this helped me.. http://www.allfordmustangs.com/Detailed/614.shtml
