All Small Six Vacuum leak at Intake CI Head

[65coupei6]

My FiTech has been acting funny. So I was checking around and look what I found. What do you think could have caused this?

I would say that the gasket was not happy with the fuel or something like that.

Finally took it apart. My carb gasket didn't look to good either. When I removed the intake the gasket just fell apart. But, it did look good around the ports. Just cleaned everything up with water and will put it back together.

Marco, did you check all flat surfaces for warpage?

Hi Marco, so was there any Vacuum Leaks then? The gaskets do look like they were holding around the ports.

Yup, I checked for warpage with a straight edge and a flashlight. All good.

There was a huge vacuum leak. That first gasket was just torn in two. 91 Octane Califonia gas. Lol. The FiTech was over compensating and brining up the idle. It runs so much better now at idle. Even got the rpms down to 850 from 900. Tomorrow I will take it for a drive.
