Mast 235 vs trickflow 235 this is what i pretty much have it narrowed to for heads on a ls2 402 4in. stroke and bore, post up what you think but post WHY !! dont just say "mast" "trickflow" give a reason..
now the Trickflow "advertises" like 8 more CFM at .600 than mast, but who knows if their numbers are bogus on TEA's website, they have some pretty rediculous exhaust flow advertisement....
but also, the MAST is an 11 degree head where as the trickflow is a 13 degree head

The point is don't just make your decision on specs because there is a lot more involved than port size and CFM on the flow bench. The key is port velocity which does not show up on the flow bench.
There is test this month between two Mast heads in GM High Tech Performance magazine. The smaller cathedral port LS1/2 head and the bigger square port LS3 head . The square port head tested at ~30 CFM more than the smaller cathedral port heads. Guess what? They made almost the power within a couple of HP but the cathedral port delivered much better low RPM torque.
Forget the specs. My LS2 with GM 243 heads CNC by Lingenfelter and a very small GT-11 cam made 473 rwhp recently.
Also check out the TF225.

I dont think you can go wrong with either head. Both are going to make good power. Long as you buy the right parts for your setup name brand isnt really going to matter. When you are talking about top quality parts trickflow, mast, afr and others like that, it isnt going to matter. If you are talking budget heads vs a top name then yes it will be harder to obtain the big power numbers.

Iv been talking to someone from mast thru PM on here, and he wants me to go with the 245, when i asked him why for my 4 inch bore he said because its not stock displacement, he said he would recommend the 215 or a 235 with a stock displacement he said for a bigger cube motor like mine a 245 is the way to go
