My original post was "Surprise under the hood" I followed Tech Inspectors advise on the build with Edelbrock Performer RPM alum heads and Howards roller cam. I ended up adding Comp Cam 1.6 roller rockers. When it came time to drop the distributor, I rolled the engine over to find TDC on #1 and had no compression. I had originally set lash at zero per instructions and went 1/2 turn more. I removed the valve cover and started over on setting the valve lash. I could only go 1/8th of a turn more without loosing compression on that cylinder. It feels right on the push rod so my question is, is this normal? Did I have the rockers too tight therefore holding the valves open? Please advise. Thanks in advance.
