Ok my problem is that my b20vtec sounds like it is running on 3 cylinders. It is a fresh rebuild: cp pistons 11.5:1, eagle rods, stock headgasket, extrude hone b16 head, skunk2 pro1 cams and adj cam gears. What i am thinking is that since the block was decked .007 and the head i am not sure about, should i have to mess with my cam timing? Only cel is vtec pres. I am getting spark in all cylinders along with fuel. And my compression is good. Any ideas are welcome, but i am wondering if i would need to advance or retard my timing.
