ok check this out buddy.. if from what i read if i understand it correctly (i may not) but if your timing chain is NOT installed and your head is bolted on with cams an valves all installed ect. and your spining the crank.. your prolly bending some valves... i've never tore apart an sr motor an tried this.. but i know on my datsun l20b motor and toyota 22r motors if you have the head bolted on an no timing chain an you spin the crank it will bend valves for sure.. just a thought man like i said i might not be correct an may not understand these motors as well as the rest of you guys.. but i've seen it happen on other motors.
also if the chan is installed on the crank sprocket it could be binding up aswell.. had that problem on a ka24de
good luck man!
