I seem to have lost this gasket. Does any one know what size it would be to replace or should I get ahold of Rick for one that he has specifically for these?

 

prob have to get it from them. Ive been looking for a metal gasket for that side with no luck

i also cant find a metal one for the driver side either

 

Depends on the crossover flange.
If oring'd.
Just GM driverside crush gasket.

If flat no oring

I can get some cut
You can cut your own with exhaust gasket material.

Could also try hi temp sensor safe rtv.

 

the make your own gasket stuff doenst last long, thats what i have on mine and its already blown out

how much do you guys sell the driver metal gasket and metal gasket for your manifold for? I called and left a voicemail with you guys

 

i used rtv on mine and its holding fine. Just make sure both surfaces are clean and flat. I used a file.

 

I will need to get some cut. Think they are 40.00 a set.

 

yea both mine are nice and flat. im going to try to make a new one today and incorporate the factory metal ring into it

i had my driver flange CNC'd it should be pretty even. The one i made for the turbo manifold so far has held up but who knows for how long

is 40.00 a shipped price or plus shipping? and are yours metal/copper/gasket material?

 

If you are building your own flanges
oring them for the gm Crush orings.

the gasket material I can have cut is a fiber/metal core gasket. Typical old school exhaust gasket stuff.
Copper takes the price over 100.00 a set ..

 

I'd recommend just using ultra copper hi temp rtv. Should seal perfectly as long as the surfaces are flat.

 

just straight rtv nothing else?

Ive never had luck just running RTV on anything exhaust wise unless its further down but right at the manifolds that see 1000+, rtv is only good for about 650, i usually spray my gaskets with a little copper spray or a light coat of rtv on each side
