your lifters should still be pumped up, they don't go flat when you shut the engine off. The forced air method is a great way to tell if everything is right. This is how I learned I burned up #3 in a S/C'd 440. You'll here the air blowing into the block if you have a leak. Have you puled the cover and slowly turned the engine over watching each valve open and close? I mean the car is running, you did pull 106mph, which isn't bad for your set-up. How is your carb set-up?
