Super victor intake and valve cover clearence

Hi,

I am running a super victor intake together with the MOPAR valve covers, we had some clearance issues with the intake and had to cut a small section of the cover to bolt properly. However we are still facing some oil leaking through the valve cover gasket. An ideas on how we can solve this issue without removing the intake and grind that little humb?
Are there any thicker gaskets out there? I have seen some spacers on ebay as well... Don't know if you recommend to use that.

Attached a pic of the isuue.
