[QUOTE="fallingup693, post: 12878422, member: 107012"] So today i did a spark check again and had spark. I also let the fuel injectors run onto a rag and there was plenty of fuel coming out. So I did a compression test and tested the cylinders. All of them read exactly 70psi. Is this normal for a newly put together motor before it is started for the first time? Or should I be really worried.... Did I do the timing wrong again? Or maybe the valves aren't sealing properly? I got the extra heads off of an aviator motor in a junk yard with about 60k miles on it. Maybe the valves were bent to begin with? When I took apart the aviator motor to get the heads off for use on my cobra I noticed that the secondary chain was broken..... hmmm [/QUOTE]
