Joel,

I think what I am trying to figure out is if you can set the 3.4 intake manifold on the 3.1 Block? I am not sure if this is even possible...If so it it would give me the option for the 4.3TBI?

I am not sure that this is even possible? Otherwise I would jsut go with the roller rocker arms and try to get the 3.1 heads polished and ported
