Hey guys. Just wondering on what would be the perfect plug with my setup for my z28. I currently have NGK TR5IX plugs gapped @ .050 , and I'm throwing a P0300 code (random misfires) 200 miles after my heads/cam swap. I had a buddy come over and hook up his live scanner and cylinders 3 & 5 were misfiring 'the most'. I'm thinking maybe a colder plug, or a change in gap? Input is appreciated. Thanks =D

*edit* guess i should've listed I installed PRC Stage 2.5 LS6 heads & TSP 224R Cam
