Crower Beehive Springs?

[Jr. Mechanic]

I found lafrad's thread bout the Crower springs : http://www.jeepstrokers.com/forum/viewt ... f=5&t=1433

I'm looking to do this setup in conjunction with my build here:

According to the machinist (who is taking forever, by the way) he could not get the seat pressure low enough with the Hughes springs. The Mopar Performance springs seem to be unavailable and I like the looks of this new setup.

Is this a sure thing? I don't want to purchase more parts that can't be used. I'm looking at the 68193 springs, 87035 retainers, new stock 4.0 locks, stock 4.0 intake valves, and stock size stainless exhaust valves.
