What are the best flowing big block heads? I'm talking aftermarket heads rather than factory. I also mean something generally available and useable rather than full-out race unobtainium type stuff.
Steve, for the coin i'd say the Indy EZs, they flow right around 290 OOTB & can be opened up to a max port window quit easy & then they will flow 320+ with no other work, thats a bolt-on, now indy had a special way back for 1800.00 bucks, but that was a good 4-5 yrs. ago, it came with heads, pushrods, head gaskets if i'm not mistaken, these heads OOTB with the small window will support 600-650 easy, i've heard good things about the stealths for the $$$, it all depends on what HP level your seeking, if its around 500-550, OOTB eddys/stealths will support that.
