I agree with Prevo on option 3. The Vortech heads and Hot Cam are a proven combination over and over again. If I was building another engine I would probably go with a similar setup and save myself a lot of what I spent on my AFR's.
Also I can attest to the MAF system being a pain in the ass to tune on a performance engine!
