Best heads for fi?

You can't beat the L92/LS3 heads for mild boost in a stock configuration. Even ported 317's or 243's usually fall short of stock LS3's. One of the best bang for the buck heads out there. They may not be the best for a high boost all out rig, but they will do just fine with mild boost.

Well I was referring to compression where some forms of FI benefit with more or less than others. 317's on a 5.3 would suck in my opinion. He might benefit with 243's milled down to bring CR up to 9.5-10:1 with the KB blower, no?
