Two different heads.
One is 346236 and the other is a 14081045
They seem to be similar with same size valves
Will this be ok to run?

By the way, one head has these large double stack washers under both valve springs, and the other one only has them under the intake valve springs.
I plan on changing valve springs but will I need to keep the large double stack washers?

Also, how do you remove these large double stack washers ? ? ? I tried magnets, air hose blast, and spray de-greaser thinking they were sucked down with a film of oil! Please help! Thanks!
