Intake Leak

When I removed the intake when it starts burning oil there is about 1/8 inch thick RTV on top of the block that seals to the bottom of the intake. If it bottomed out the RTV would squeeze out.
Now a thicker gasket might be needed, that I could try. Maybe one that will compress more than the .060 Edelbrock gasket I used first.
I am using Magnum heads and the bolts pull the intake down tight.
Thanks for taking the time to try and help me Bad Sport, I appreciate it.
