I just recently replaced a head gasket on a 97 chev z71 witha v8 vortec and every once and a while it bogs out really bad like its missing or the timing is out, but sometimes it runs fine. I thought it might be the risers or timing chain or something like that that i put togather wrong but i am not sure and i dont really want to take it in, what do you guys think?
