hey man, there were no DASH 8v heads. the DASH head is specifically a 12v head (2 intake, 1 exhaust per cylinder).
if your looking for a head to replace the one on my old motor, any 8v head off a 4g62, 4g63 and maybe even 4g64 can be used. i would investigate the 4g64 heads (also possibly same model sonata that the MPI comes off, g4cs motors for hyundai) as they apparently have bigger ports and valves than the other 2. and some are standard hydraulic lifter roller rocker setup, so that cam will go straight in! (or if you wanted a solid setup, then you can revert back to adj tappet and cam from a cordia/starion etc..)
