Intake manifolds are a fetish of mine. I've messed with them all at one point or another and actually used to enjoy changing them. Anyway, if you have aftermarket aluminum heads, the Edelbrock Performer RPM is hands down the best street manifold ever made. The Air Gap Performer RPM is even better, but possibly a tiny bit taller. My all time favorite intake is the Dart single plane Oval port which has been opened up to Rectangular ports. Very, very tall though.
