J Heads

if you go 4.10s, and if you truely have 10:1 static compression ratio (at least) then I'd go with the EX247H, it's the next step up from the 268. If you go lower then 10:1, or want to run 3.91 or numerically lower, then go 268. You wont be disappointed. The heads should cot aroun $6-800 done properly, with good parts. Make sure the springs match whichever cam you decide on.
