I took the sparkplugs out and tried to turn the crank,i even had a buddy of mine with both of us on each cam gear.we both pulled are cam gears to the left.nothing budged.I put the car in drive and it was easy to push the car in each gear.that seemed weird.did'nt think i could move the car in gear.I'm really excited to take the head off since last time i did i did'nt know how to work a torque wrench.This time i do.and the second time around "which this will be "should have a beter outcome.i'll know what and what not to do.since the head could'nt move at all,i'm thinking the top end somehow is messed up.i'll replace the valve stems,seals,and have them plain the head.opinions are wanted.:icon_neut
