Default Best heads for fi?

Heard some mixed reviews about the l92 heads. Just wondering what some of you are running. Going to be running these on a 6.0. Thanks

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.

L92's get a bad rep... I run 24# boost and 18* of timing on my 403 w/ twin76's with no issues. No meth, no N20 for cooling... just a big I/C

Depends on what type of FI you are going!

Doesn't matter what kind of FI as long as x, y, and z are taken care of... coolant system/temps, oil temp/pressure, timing, maintaining crankcase pressure, iats, fuel system, fuel used, etc. etc.

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?
