Part # for Dart 13* Intake Gasket?

[TheJet-09]

I was hoping someone might have a part number for an intake gasket, Dart 13* (raised runner) heads?

Dart calls for a Mr. Gasket 143, which looks good port wise (2.26" x 1.35"), but it is only 0.060" thick. I'm looking for something 0.120" thick (at least that is what is currently in there)?

Fel-Pro has a 1288, which is 0.120" thick, but the ports are smaller (2.15" x 1.25").

Any help or suggestions are appreciated!

1288 and trim it?

That's the plan for now. I hate to bother an engine builder when they're not profiting from it, but there isn't a whole lot of information out there (at least that I have seen).

Thanks for the response!

My work stocks them in Cometic, I used to have that gasket listed in our eBay store, but don't anymore. Call Speed Custom and Performance tomorrow at 636-677-1320 and they'll hook you up.

I believe you need this one: Cometic Aramid Fiber Intake Gaskets C5541-125

Thank you for the responses. Ironically, Cometic doesn't show the 0.125" gasket (at least on their website), but they do show the same model, only thinner (0.047" I think?). Summit does show the 0.125" but not available until next week.

I should know soon if the Fel-Pro will work.
