one last thing youll need is the 1/8npt allen key plug that will plug the oil supply hole in the bottom of the head. as far as getting a head id start off with a b16 head(theyre easier to come buy and supposedly flow a little better than a gsr head. for a computer id always have to recommend hondata especially if you plan on have high compression and nitrous, but if worst comes to worst id get something obd1 converted with a vafc or something along those lines. and for the motor some eagle rods with some type of forged piston(wiseco, endyn, JE) will do the trick, the internals really depend on how much nitrous u plan on throwing at them.
