I think you should post a pic of the seat. When the seat is cut for inner springs they usually only cut it back to the i.d. of the inner spring. Likewise when cutting the guide for viton seals, they usually only cut the guide. The spring locators are all .060" thick. Instead of cutting the seats again you might consider getting retainers or valve locks that will give you .050" more spring height. I sure wish he would have only cut the guides down to the inner diameter of the spring. I even brought him a full set of springs locks and seals when i had them cut. Too late now, gotta work with what i've got.

How nice of your to give no advice whatsoever and then come in aggressively stating your opinion. Your input is not needed. Move along now. You are only upset because you don't want to hear the truth. I didn't give my opinion because it has already been said. You need to use a locator to keep the bottom of the spring from walking. That is why there is normally a spring pocket. Since yours has been removed, you need a new way of locating the bottom the spring.

Anytime they cut a mopar cast head for duel springs you lose the factory locator...I have a set of DC stage IV heads that have had a .750 roller cam with 275 lbs of seat pressure under them for 25 years with zero problems! The only thing that is needed is some sort of hardened shim, which you will probably use anyway to set the spring height. 8010894-pomona.jpg (135 downloads)

I thought that I needed them and it cost me a oil pump and a pump cover. Could have been way worse. Brian 8011188-ValueSpringLocators012.JPG (175 downloads)

Therefore the cups could cause me to need to get offset locks. The outside edge of the seals fit pretty flush with the guide, so i don't think there's much chance of them getting chewed up. There is only .050" of movement to be be had with the springs. And there is no pockets to jump out of. So i think i'll go ahead and skip the cups and just run shims (so far everyone needed a shim)
