Burn on the intake manifold
I have a newly rebuilt 327. During the first 15 minutes of running I noticed a small burn mark on the Intake above #3 and #5. (the Chevy orange now has a nice black spot)
The black mark is about the size of a quarter. I was going to attached a picture but learned that I can't...
Any Ideas ?

With the intake installed it's a bit difficult, but if you can maybe slip a 2x2 piece of stainless steel between the intake gasket and the head by maybe loosening the intake bolts then you're golden. I'm not recommending that you do this, it's just a possibility. Blocking the heat crossover keeps the hot exhaust out of the intake, providing a little cooler fuel/air mix and also helps oil temp from the bottom of the intake. Other side is that the cold weather driveability may suffer a bit..
