Intake gasket differences

I made the picture above because I needed to show the differences of stock carbed intake manifold gaskets, and how you can trim material from the short runner style to have tall runners like a reverse runner '76 manifold or some aftermarket manifolds like the Camden SC, some weber manifolds etc, while retaining a seal around the ACV port, which the mid to late '70s gaskets lack. It was never intended to show the differences in relation to EFI on the later engines.

But to answer your question, the T2 and 6 port engines have the same bolt pattern and similar intermediate runner location and height. Mainly the end plates are different. However there is an aftermarket gasket which has tall connected runners on the end plates to work with a T2 and a 6 port. I got it from Atkins. Kind of a universal gasket for 2nd gens and the GSL-SE.

Sorry, no pictures handy, and it's harder than heck to deal with pictures on this forum because it has new software which causes all pics to have a size of -1 and they don't display for me. I'm using an older OS. That's why I made such a big deal out of that picture above, hoping that it would work. I checked it on a newer computer and it does display on a computer with XP.
