I currently have the new Diamond Performance ones in silver. Diamond did a good job cleaning up the look with redoing the molds.

remove spark plugs. install two temporary 3/8 studs(cut the head off a 3' bolt). slip on gasket, slip on manifold,( it will not slip off studs once pushed up to head). install bolts. Remove studs. install bolts. install plugs and wires.

enjoy the compliments of having a different, cool sounding boat.

What material are they made with

I think he is probably talking about regular Lightning tubular headers.
Your'e going to need the right length header bolts or studs.
Use a gasket like this for ease of install http://www.summitracing.com/parts/sc...make/chevrolet

Lightning tubular headers dont run them in the salt

Hey Griff, do you know for sure I will need longer studs on a 502 EFI? If so, what is the part number. And thanks for the heads up on the gaskets. They are ordered and have been delivered.

Did you get the headers installed?

Do the KE style perform better than the Stainless Marine?

from what I have read and heard there isn't much that out performs these KE style manifolds
