Default Superram Gaskets?

Well in a couple weeks I will be installing my used SR. Right now I have no gaskets at all for it. Is buying the Accel kit the best wat to go? Anyone make their own gaskets? I have removed a whole bunch of material from the plenum to the runners and inside the runners but have not done much work where the runners meet the baseplate. All info is welcomed. Also, regarding the surface texture after porting. Since this a dry intake and I dont plan to spray it, can I mirror pollish the entire unit on the inside with crossbuffs? I imagine so since it would be similair to an extrude hone or to the texture of the stock runner tubes.

Thanks for your help.

Yep get the accel kit. Just make sure when you get it that the large plenum lid gasket isn't ripped. I got one from jegs once ripped. I called them and they overnighted me a new one right away.

I looked at the Accel kit on Jegs. The runner to plenum gaskets looked like one big hole. Is that normal or right? I im agine it could hurt flow.

Yup thats what they look like. I think the reason they look like that is that lots of people cut out the seperator in the plenum between the two runners. I personally haven't.

Wow, the speed of the replys is awesome! So for the plenum to runner gaskets you guys just cut out the metal dividers in the plenum and them mold the runners to the oval shaped gasket openings? Anyone got pics?

Thats what I did. I dont have any pics.
I picked up some extra runners (for direct port N2O) that were ported much larger then my plenum openings.
So I went in and started porting my plenum, and after a while of removing a lot of material, I grew sick of the divider and cut it out.

So all I have is a big oval, with radiused edges.

I dont think this does anything for performance, it was just "in my way" when I was porting my plenum.

Anyone have the Jegs part number for this set? I can't seem to find it in the catalog. Thanks!
