I am thinking about getting a cam from exospeed but will told me that he wasnt sure if( zc vtec ) head was the same as a d16z6 so i got to send my cam in for him to do it right , i dont know if i can make it w/o my car that long, does anyone know if these two heads are the same????I have heard people say that the cam was a little more aggresive, any info would cheer me up!
