That's funny. You do so much porting work that it turns into a thin piece of aluminum foil LOL maybe instead of all that porting you can just push luminum foil over the top of it and make a template?
The problem is when you port the intake, the bolts are strong enough but the manifold isn't.
Don't ask how I know. It's a bunch of welding to fix it. When I port an intake I make sure I write on the receipt do not pick up engine by intake manifold.
