Default Intake Manifold Question

I have a 1967 327 - 300 using an Edelbrock performer aluminum intake.
The engine was rebuilt in 2006 and the block was decked.
I have been going through intake gaskets every few years - an internal vacuum leak.
Any thoughts on what the best gasket is to seal the leak and any other advice.
A friend said since the block was decked I may need to take a few thousands off the intake?

Thanks in advance for sharing your knowledge.

What gasket have you been using and having issues with?

Edelbrock recommends the Edelbrock #7201 gasket...which is .060" thick. Same as a FelPro 1205.

Don't machine the intake.

Most gasket mfgs say not to use sealer..
But I use permatex aviation gasket sealer.
The brown brush on kind in the jar...not the tubes.
I have never had a leak.

And if the block has been decked THAT much, there are thicker (.120") intake gaskets available.
Without any gasket, is the intake resting on the "China Wall"?

Bill - I used a FelPro last time which was about 2 years ago.
I may try the Edelbrock one this time ( 3rd gasket)
Any specific reason why I should not machine the intake?
I just want it to run well - it has not been a major issue - sometimes it will idle a little rough and if I drive for a long time and get t hot when I stop for gas it will whistle for a minute or so on start-up.

Bill,
It appears to seat just fine.
Who makes the thicker gasket?
My thought is to use the thickest gasket - the aviation sealer and some ARP bolts this time...

Your thoughts appreciated...

Mr. Gasket #106 is the closest port size to the Edl-1205 but is .120" thick.
Will work fine...
