My intake manifold fab.
 

I don't really do much aluminum work. I need quite of bit of work still. My consistency isn't great and I need to work on my starts and stops. I incorporated the velocity stacks into the plenum floor. The welds from the runners to the stock flange suck. I tried my best to clean the cast aluminum but nothing worked too get it perfectly clean. I thought I would post it up on here and hopefully get some advice on what I'm doing wrong. Thanks.

What you need help on? Clean, use some carb cleaner.

Need more consistency with head and filler. Don't stop/start so much. Clean cast runners with A/C current, brush off contaminants, repeat a few times. Done. Did you do those velocity stacks with a router?

What's the purpose of the stacks if their flush with the plenum? I thought if your using stacks then to mount them so their raised inside the plenum? Overall looks better then what I can do.
