Damn cast iron heads!

I've never messed with the iron heads before but that inner washer needs to come out somehow. Where the old stock spring sat is the same location the new dual springs need to sit flush and at the same height. Hopefully thats not a machined boss on the cast iron head that isn't present on an aluminum head.
