ROFL!

That tape is "easy release" for painting. The aluminum tape is teh shiz.

That or this 3M vinyl tape I've used to close manufactured houses with. This stuff sticks to the plastic film that goes over the open half of the house in the middle of a rain storm...

Finally updated the intake numbers. Exhaust flowed the same as before so I left the old numbers there for exhaust.

those are still some damn good numbers... wonder how far they can be taken

and this is with 1.76/1.42 valves, correct?

[SappySE107]

3900 heads have 1.87/1.52 valves

[robertisaar]

the hell was i thinking of then?

regardless, it's still impressive and more than expains the 3900's awesome power curve.
