i will like to know if over adjusting the RR will case the motors compression to drop a Little or not have compression . i checked the ring in the piston and there fine the heads also have no issues.
If you've tightened them so far that you're holding the valve open at TDC, then you will not have compression. Put a vac gauge on it and see where you're at. If vac is real low - or jumping around, there's a good chance you have them too tight.
