stony brook,

Well this happened after the dyno the other day.
idle no sound, at about 1200rpm the tapping starts, then will go away at idle again?
So far I’ve change new rockers (cast) new lifters
Still has sound.
I’m trying to get some input before I rip the head off.
1g head on 2g block
Head work
+1/+1mm valves
Super tech comp plus valves
Super tech duel 9*lbs spring
Gsc 280’s
1/2 boosted head studs
I will be doing more diagnostic tomorrow, again before I rip the head off
Cylinder 1-2-3-4 i labeled from passenger to driver
Compress 140* cyl 1 100 / cyl 2 100 / cyl 3 140 / cyl 4 120. I will be running test again when motor is cold tomorrow
