Going to be installing some new valve springs ( comp 980 ) It been suggested to not install the stock cup that the spring sits in ! Does not installing the cup cause any problems ?
What was suggested to be used instead of the cup?chriss4655 said:Going to be installing some new valve springs ( comp 980 ) It been suggested to not install the stock cup that the spring sits in ! Does not installing the cup cause any problems ?

chriss4655 said:New springs are on and heat cycled a few times, went for a ride and my high rpm stumble at the top of thrid is gone Have not had a chance to check the pressure on the old ones yet! No cups and no shims , the heads have never been off so no machine work has been preformed on them. Installed at 1.7@ 88lbs closed seat pressure go figure I rounded up a boat load of shims and didn't need a one !!!
