Help! Thermoquad gasket 71 340 - which one?

i would use the open, i would not want a unsupported gasket over the intake opening. It might be rare but there is always a chance of a piece of the gasket cracking off and heading down into the engine,,,,, just my two cents...

Good advice - and it makes sense.

I'm not after the 100 point resto - so I'll order the open 1/4" insulating gasket. If I remember properly, I think it's Fel-Pro 1908.

Thanks again for the advice. :prayer:
