Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
There used to be a good pic on here showing the casting flash. I think some of the Vy's couldn't use 1.98 even with the thinner walled push rods ? Many people would have reconditioned heads by now so could be form nay model but you would hope they clean those up when putting in new valves and checking the heads (supplier that is).You don't have to run new push rods (except with the 1.98 ratio) but I would highly recommend new push rods when fitting new rockers. I've seen a few pulled apart and most push rods I've seen have wear on the end.
does it matter where the crank is? eg valves open closed for the torque setting? thanks Justin. love your channel

Was the wear on stock rockers or high ratio ? For the push rod wallsHi mate,
I have seen pictures of push rods that fouled on the casting flashes where the push rods pass through the heads but I really can't remember I saw those unfortunately.
Push rods spin when you have flat tappet hydraulic lifter which spin on the cam lobe, with roller lifter there is nothing to spin the push rods which is why I think you get wear in the rocker push rod cup/push rod tip.
