Default Which LS3 head has the most Potential?

Which LS3 head has the most Potential? I'm working with a solid roller with 710 - 740 lift depending on the rocker ratio so what LS3 head do you think has the best potential to fully utilize my cam.
Everyone's got an opinion....

The TFS or PRC heads would get my vote. I bad the prc 260cc aftermarket ls3 heads on my 408 but now that the TFS are FINALLY out id try them.

Yeah I'm with you I looked at the bore size for the TFS heads 4.065 vs TSP i really believe they used a 4.125 or larger bore to get those #'s(they do have a great price for LS3 255' as cast 1600.oo). Also my cam is a solid with over .700 lift so when I do get another set of heads I'll get Greg G. to go though them and make sure flow doesn't stall at .700 but flow up to around .750 no use of having a cam this high and a head that can't get me their.

Just so you know, All-Pro has an LS3 head too. Coming from them you can expect it to be top notch.

They use LS7 rockers though. Unless you want to go T&D or Jesel

Yea WCCH already got that LS3/ LS7 port configuration a lot of port sizes,I been had these L92 bare heads from 08 or 09 $179.ea.so I went LS3 style. I have the Vic Jr. LS3 style intake....T&D rockers are on my list for 1200.oo by T&D... Jesel's are 1900.oo for the light wt. and 1615 for the regular shaft mounted rockers.Also WCCH are 3200 bare....TFS with some port work to match the cam will be around 3 flat and flow will extend to 750 lift range.....Need time and $$$$$$.I've put this engine on paper some time back and I change a few things here and there like Hyd to Solid...etc..... but the overall engine is the same 408 12.0 comp engine....
