Ok i need to know what gasket to get. I have a ported Cobra intake- was told that it was ported to "gt40" gaskets, So is that the Felpro-1250 intake manifold set( i think thats what the p.o. told me). Needing a little help with this port dimensions for the gaset are 1.28 by 2.10, i dont know what gt40 head-port sizes are, so hopefully someone can help me. Also they say are made of ruber-fiber for precision trimming, so maybe i can just trim to fit if needed.
Thanks for the help

 

1250

 

So thats what i need, i wasnt quite sure thanks alot

 

OK, so the gasket showed up today, seems like it took too damn long, anyhow was just wondering if anyone knew if this ir the right gasket? B/c it seems big but its probably just me. Thanks

 

what do u mean by big??? like it doesnt line up with the porting just rite??? if thats the case u should be ok... take a picture of what your talkin about and mayb we can give u better info... that gasket should work... whats what im using... well goin to be using and it seems to be the rite size

 

I havent even put it on yet, it just looks long in th epackage, and when i orderd it, they said complete set, i thought it would have the upper to lower plenum gasket too, but it doesnt, Anyway will that work with Cobra intake(ported) and gt-40 heads? ive heard that gasket is the "gt-40" gasket or should be the same size? is that true
Sorry if this is a dumb question, b/c i feel it is[:-]
Gasket openging= 1.20 by 1.00?
Does anybody know if that is the port volume one those heads?
