So bigger? Maybe im just not undersanding the concept. The guide states to port match, scribe the inside of the gasket which I did.

Lol sorry, I'm ****ty at explaining things if I can't point to it...

Basically what happens is you match the port perfectly to your head/intake. When you torque down the bolts the gasket expands, which intrudes on the ports. ALSO, the way you had that gasket laid on the head/intake, will not lay the same when you install it. Basically, the gasket will probably sit lower in the port, therefore blocking part of the roof of the port. Only way to fix this would be to stick dowel pins of some sort in each side of your head/intake to make sure your intake fits on your head in the same spot everytime.

I hope that makes sence

Gotcha, yes, I had to hold the gasket with my hand, I mocked it up using the intake bolts and it sits perfect, believe I stated that in the thread I made. Shouldn't be a problem using a pencil or some other device to hold the gasket in place. Thanks for the advice.
