What am I doing wrong?? Timing cover/post cam install

Hi all. I just put in a new comp cam, lifters, timing chain, and tensioner, but I cant get the timing cover to seal. I went through two gaskets both slip out the top of the timing cover when I start toqruing the cover down. I am using permate/ liberal amount on both sides and a felpro gasket.

-Now I am getting worried about trying to get the intake back on. This is my first cam swap and I feel I may be in over my head.

Any tips or pointer at all are appreciated!!!!
thanks

oh ya its a 273 with the bolt on timing tab and all
