Okay, a new development. Hopefully someone will rescue me from talking to myself...
I arranged to buy a set of Edelbrock E-Tec 200 Vortec heads (assembled) for $500. This is certainly a no-brainer. Unfortunately, this means the RPM manifold that came with my motor is useless, since the Vortec heads will require a Vortec intake. As I understand it, the extra expense is worth it.
Would you folks recommend an RPM, or an RPM air gap for my intended use?
