Indy LA-X vs. Eddy heads

Didn't say you did, but cool, then answer these questions for the answer you your question...

My goal....I want a car that will hold its own on the track (maybe mid-low 12's) if I decide to take it to the track. It must run well in traffic and not overheat in stop and go traffic. Right now I am most likely going to go with a 408 probably around 10:1. Cam selection, carb and intake are all still undecided. I am waiting to see how much of the budget gets ate up by the body shop before I start buying motor parts.
