by your same logic 243 heads would be a good choice too because they are cheap, the bigger bore would unshroud the valves more etc. only good thing about the L92 heads is that they fit on a 4.00 inch bore. if you want to you can buy LS7 as cast heads, which would still outflow L92 heads. the only reason why you want to run a bore bigger than 4.125 is so that you can get LS7 heads on the motor in the first place. its self defeating to put inferior heads on a motor in the first place. lets put L92 heads on an LS7 and expect it to produce more hp :ROFL:
