My Heddman 1-3/4" came back from Moore coatings...sweet. I'm checking my exhaust gasket, felpro #1424 to the heads....the port size of this gasket is too big! Port size on #16's measures 1.75" high x 1.13" wide. Checked the gasket to my header and falls outside the machined weld sealing surfice.
What is the best exhaust flange gasket to use with #16 heads stock port opening heddman 1-3/4" headers? Mr. Gasket #550? |

I've used the Fel-pro's with D's & 1&3/4 Hedman headers with no problems.

Scott,
Why did they make the port size bigger on the gasket than the port size on the head? Seams to me it leak like a seive. Anyone else shed some light on this? |

Here's a couple of pics of a 1424 sitting on an old #62 D port I have laying around in the garage. Does your's look like this?
I have another set of #62s on my bird with the same hedman header and they don't leak. Maybe you got some different kind of gasket(?) pic 1 pic 2 |

MikeB...
Yes they look like your pics. Over sized for the port. Mr Gaskets are closer to the port size, What gives why wouldn't Felpro make a gasket that matches the port size? |

I installed a set this week and like the fact that they're a little larger. There's no chance that the gasket will block any of the exhaust flow. With casting irregularities it makes more sense to open up the holes a little.
