882's are open chamber 76cc crack proned smog heads.  They are okay for a bone stock, low HP engine.  DO NOT get them hot or they just crack.  A 160 thermostat and a 3 or 4 row radiator are your best friends. ;D

make sure you're reading the # carefully and that it is the correct # sometimes 3 look like 8's etc. Not a very common casting # if it is correct.
