Ported intake / exhaust manifold gaskets ?

[EricB]

Hi all

Does anyone recommend a resource for ported intake exhaust manifold gaskets?

I was opening the intake holes on one 240Z gaskets on a spindle sander and I have mixed feelings about the results...

I thought I had seen some larger diameter intake exhaust gaskets on the net somewhere but can't find them anywhere now

240Z intake gasket port hole is about 36mm

I need to get to 40mm for my specific application...

Thoughts?

Thanks,

I don't see the enlarged gaskets I purchased years ago on their site, but it wouldn't hurt to shoot'em an email to see if they can help.

These guys made the Nissan Motorsports intake/exhaust gaskets that never, ever leaked and you could grind on them for ported heads.  No longer available but a phone call might get then built again.

Looking at their site I think the gasket was style 706 which is discontinued.
