I am looking for a better head for my 346,I have ported 853 heads 2.055/1.60 valves. It has a forged bottom end,242/252 610/600 112 comp cam,ported LS6 intake,80mm tb. any ideas other than allpro's or trickflow? Has anyone seen any flow sheets from allpro?

 

I was in the same boat awhile ago trying to make a choice. The TFS's are what I chose. Not because of the flow but because the Allpro's have a 230 runner and the TFS's have a 215. Sucks because I can get a pretty good deal on allpros
