alright guys I've searched the site and the web looking for answers. I just installed my cam 216/224 crane matching dual crane springs comp retainers new rods lifters the works onthe top end. at night when the air is cool it runs great during the heat I'm chained to a tree. Does through the random multiple cylinder misfire p0300 which in turn throws the knock sensor p0332. Hooked up to a computer everything looks good fuel air maf cats. i'm in Memphis with no tools to work on this and the $92 dollar trip to the shop says burnt or bent valves won't close may be due to the new cam blah blah blah..

Any advice would be much appreciated
