Mast LS3 256's or Trick Flow GenX 255's ??
LS2 about 13.1-13.5cr, 700" lift, Super Vic with carb, and 200-400 nitrous. Minor weight reduction
I am liking the Mast heads but the more I look the more I see they are very much alike and I think I can get the TF's a little cheaper. Any thoughts or at this point is it more up to preference?
Didn’t know whether to post this in the internal or external area but I found a few more posts about heads in here.

All those heads which has come up are great no way to go wrong -however there's new mayor player coming to the arena, RHS has a small bore ls7 head with crazy flow numbers using the ls7 intake which takes away the reason for a high ram carb style single plane intake and promises big power worth considering....

The Mast heads are GREAT heads also TFS 255 but.... I like everything tweaked to my spec's. If I were buying any LS based non racing head it would be a bare set of RHS non Cnc'ed heads. Then set-up to match my engine combo size RHS heads can get just as big as Mast 305's or as small as 260 cc's. Have my boy Chris Frank port'em. And Mast/TFS heads are just a thing of the past. They flow better than the Brodix and other heads that Chris has done he has a post about there RHS stage 1thru3 on yellow bullet. He also has a post on there factory LS3 heads making 756fwhp with a combo (duration is about the same I do have more lift both pump-gas) very similar to my combo 414 vs 408. They used stage 2 heads and I am using stage1 heads. I have both the Super Vic and Vic Jr both set up for EFI. Stage1= More TQ mostly 4 street use.
1 thing I will never understand why get heads that flow over 370cfm and use a intake that WILL NOT SUPPORT the head for it's intended use.. Darn most people would have to run a cowl or go hacking on the hood. Hemi Shaker on a Cutlass any1 ?

The factory can support any of our needs it really comes down 2 cash flow because RHS bare heads are dirt cheap. They just would like a custom Cnc program.
Chris also stated that they made 720fwhp with a hyd roller on a 414 with there small bore RHS head 390cfm @ 670 lift. 4.060 thru 4.100 bore using 2.150 int valves.
